Chapter 1 Summary – Wrath of the Triple Goddess – I Have an Accident in the Principal’s Office

Percy is enjoying an unusual period of normalcy in his life as a demigod while trying to complete his studies at the Alternative Education Institute. However, his tranquility is interrupted when he is called to the principal’s office, where Hecate, the goddess of magic, awaits him. With an imposing aura and a disturbing presence, Hecate informs him that she has a mission for him: he must take care of her pets for a week at her mansion. Percy, who had been hoping to receive letters of recommendation from the gods to enter New Rome University, learns that Hecate has driven away other gods with potential missions, ensuring that he was available. With few options, he accepts the task and receives instructions to arrive at the goddess’s mysterious house in Gramercy Park at nightfall. He knows that nothing in his life is ever simple, and this seemingly harmless favor is bound to bring surprises.

Chapter 2 Summary – Wrath of the Triple Goddess – Grover Overdoses on Caffeine

Percy meets Grover at their favorite café to inform him about Hecate’s mission. The satyr, excited, sees it as a great opportunity to bond with magical creatures, though Percy suspects it won’t be that simple. Together, they visit Sally, Percy’s mother, who reacts with concern and evasiveness upon hearing the mansion’s address. Percy notices her unease, but she changes the subject, wishing him luck and reminding him to bring his toothbrush. Meanwhile, Grover devours a strawberry muffin and a latte, quickly becoming energized and rambling enthusiastically about the mission. As they part ways, Percy reflects on his mother’s reaction and the mystery surrounding Hecate’s house. Something tells him the goddess isn’t telling him the whole truth, and once again, he’s about to be dragged into a far more dangerous mission than it appears.

Chapter 3 Summary – Wrath of the Triple Goddess – My Girlfriend Takes Me to the Cemetery

Percy visits Annabeth at her design school to tell her about the mission. After a brief chat with her friends, he takes her to his favorite thinking spot—a nearby cemetery. There, he explains Hecate’s offer, including the fact that the goddess will split into three forms and that her pets include a hellhound and a ferret. To Percy’s surprise, Annabeth is thrilled. Not only does she agree to help, but she also suggests using Hecate’s mansion to host her long-awaited Halloween party. Percy hesitates, but his girlfriend is convinced it’s a brilliant idea. While Percy is usually the impulsive one, this time, it’s Annabeth who insists on taking risks. The determination in her eyes makes Percy give in to her enthusiasm. With the plan in motion, they decide to meet later to grab Mexican food before heading to Hecate’s mansion.

Chapter 4 Summary – Wrath of the Triple Goddess – Turns Out I Taste Like Salmon

Percy, Annabeth, and Grover arrive at Hecate’s mysterious mansion in Gramercy Park, discovering that its exterior is hidden by a magical illusion. Despite the eerie decorations of tombstones and gargoyles, Annabeth is fascinated by its potential as a haunted house. Upon entering, they are greeted by Hecuba, a massive hellhound who immediately takes an interest in Percy, claiming he smells like salmon. Grover tries to translate, but the situation doesn’t improve. Then, they meet Gale, a ferret with gas issues and an attitude problem. Finally, Hecate appears at the top of the staircase, dressed surprisingly casually, and welcomes them with a disturbing smile. Before Percy can question her relaxed appearance, the goddess announces that she will give them a tour of the house—for a fee of three gold drachmas. Percy gets the sinking feeling that they’ve stepped into something far more complicated than they expected.

Chapter 5 Summary – Wrath of the Triple Goddess – We Break into the Forbidden Ice Cream Lab

During the tour, Hecate shows them a column of venomous eels she keeps in her house, revealing that their slime is useful for potions. Percy, who can understand them, realizes that the creatures are manipulative and threaten to bite him unless he feeds them more. Then, the goddess mentions that the mansion used to be a school of magic but avoids elaborating on its history. While Percy dreads staying in the main hall, Annabeth takes an interest in the forbidden library, and Grover asks about the kitchen, where they discover a strawberry ice cream machine. Hecate warns them that tampering with her experiments could have disastrous consequences. Percy is already uneasy about the house, and his concern grows when Hecate mentions that they will now learn how to care for her "adorable" pets. Meanwhile, Percy starts to realize that, despite how simple this mission seems, there are many secrets hidden within the mansion’s walls.

Chapter 6 Summary – Wrath of the Triple Goddess – Raw Chickens and Where to Find Them

Hecate lays out her strict rules for pet care before leaving, entrusting Percy, Annabeth, and Grover with the responsibility of looking after Hecuba and Gale. The hellhound requires a specific diet and limited walks around New York, while the ferret has its own training room and a peculiar diet consisting of raw chickens. The trio is horrified as they watch Gale devour a hanging chicken, diving into its cavity to eat. Hecate warns them never to call Gale a weasel, which provokes a furious reaction from the animal. Before departing, the goddess casually mentions her parade in Tokyo Disneyland and leaves them with magical emergency torches. As she disappears, Percy feels that the real challenge is just beginning, as the pets stare at them with an unsettling expression of excitement over their newfound freedom.

Chapter 7 Summary – Wrath of the Triple Goddess – I Go Dog Sledding

The first night as Hecuba and Gale’s caretakers turns chaotic. After cleaning up food remnants and feathers from the floor, the friends realize the pets are eager to go outside. Hecuba drags Annabeth like a water ski, while Gale entangles Grover with her leash. Percy struggles to keep up as his friends are pulled through Manhattan traffic. During the walk, Hecuba enthusiastically marks every corner, and Gale ends up perched on Grover’s head. When they finally return to the mansion, exhausted, Annabeth discovers that Hecate’s bathrooms defy logic, with toilets on the ceiling and showers spraying freezing water. Before bed, Percy glimpses a ghostly vision of a girl on a bicycle and a pair of broken glasses disappearing into the mist, leaving him with an ominous feeling. As everyone sleeps, he reflects on the fact that in his world, things never get easier—just weirder.

Chapter 8 Summary – Wrath of the Triple Goddess – Listen Closely: Weasel Butt

The morning starts early with Hecuba and Gale’s breakfast, which requires patience and effort. During the morning walk, Grover suggests creating a schedule to organize their pet care duties, splitting responsibilities among the three of them. Percy and Grover accompany Annabeth to school and part ways with a joke. On their way back, Hecuba attempts to raid a Greek food stand, but Percy manages to restrain her before she destroys the cart. Grover stays home while Percy heads to school, trusting him to handle things. During the day, Percy notices the odd behavior of his school counselor, Eudora, who seems to fear Hecate. After school, he waits for Annabeth and Grover, but neither shows up. After an hour, he runs back to the mansion, where he finds Annabeth equally concerned. When they arrive, they discover that the house has been destroyed from the inside—the door has been blown apart, and Grover is nowhere to be found.

Chapter 9 Summary – Wrath of the Triple Goddess – The Apocalypse Smells Like Strawberries

The interior of the house is a disaster, filled with blue smoke and shattered furniture. Percy and Annabeth find the kitchen covered in a strange pink substance that smells like strawberries. Amidst the chaos, they discover a gigantic, swollen Grover snoring atop the kitchen island. When they manage to wake him, he deflates after a massive belch. Embarrassed, he confesses that the disaster happened because he tasted Hecate’s enchanted ice cream shake. Before they can argue, Grover panics as he remembers the pets. Percy and Annabeth search the house, but Hecuba and Gale are gone. They consult Hecate’s eels, who confirm that both escaped when the explosion blew open the door. Grover tries to stand and help, but he’s too weak. Feeling responsible, Percy decides to track down Hecuba himself, using his last hope—summoning Mrs. O’Leary.

Chapter 10 Summary – Wrath of the Triple Goddess – I Catch a Nope

Percy heads to Gramercy Park to summon Mrs. O’Leary, hoping that his hellhound can help track down Hecuba. After several failed attempts, he uses a magic whistle created by Leo Valdez, successfully calling Mrs. O’Leary from the shadows—who enthusiastically knocks him over. After calming her down, he gives her Hecuba’s leash to follow the scent, but instead of finding her, Mrs. O’Leary leads him to an alley where they discover a small, injured hellhound puppy, trembling and frightened. Percy, moved, wins the pup’s trust with some treats and names him Nope due to his peculiar bark. Exhausted from the journey, Mrs. O’Leary disappears into the shadows, leaving Percy alone with the puppy. Though he has yet to find Hecuba or Gale, he decides that his first priority is to help little Nope and bring him back to the mansion, knowing full well that Hecate won’t be pleased if he returns with an extra pet.

Chapter 11 Summary – Wrath of the Triple Goddess – We Eat Pizza with Extra Tears

Percy holds the puppy, Nop, who gets so excited that he pees on his shoes. Annabeth and Grover, exhausted from recent events, accept the dog despite still not having found Hecuba or Gale. Nop has a cut on his back, and Grover offers to heal him with natural magic. After a quick cleanup, the friends gather in the ruined great hall, where Annabeth surprises them with pizza. As they eat, they reflect on Hecate’s missing pets and the destruction of the house. Annabeth suggests investigating the goddess’s library, while Percy must attend class. Grover, still feeling guilty, focuses on cleaning. With morale low, Percy tries to comfort Annabeth, reminding her that they’ve overcome worse challenges. Finally, they all attempt to rest, knowing the coming days will be crucial.

Chapter 12 Summary – Wrath of the Triple Goddess – An Old Friend Teaches Me a Lesson

Percy searches for Eudora at school, but his supernatural counselor has disappeared. With no other options, he decides to ask Dr. Sharma about Hecuba, but instead, he finds Chiron disguised as Professor Brunner in the classroom. The centaur explains that he’s filling in as a substitute teacher at Paul Blofis’s recommendation and is taking the opportunity to stretch his hind legs, revealing his old limp—an injury from Hercules. Percy explains the situation with Hecate and her destroyed house. Chiron warns him not to use the goddess’s torches, as they could summon dangerous spirits. He then reveals that Hecuba was once the queen of Troy and, after her tragic downfall, she harbors a deep hatred for the Greeks. Percy deduces that the hellhound might be in Astoria, a neighborhood with a large Greek population. With a plan forming, Chiron urges him to attend class before acting, reminding him of his pending exam.

Chapter 13 Summary – Wrath of the Triple Goddess – I Get Extra Time and Candy Corn

Percy fails both his exam and his school day, but the worst part comes in the subway when Hecate appears in his reflection, questioning him about his week. Unable to lie, he tries to distract her by suggesting she extend her trip. Intrigued, the goddess agrees to delay her return until Saturday morning to attend a celebration in Transylvania. When Percy arrives back at the mansion, he shares the news with Annabeth and Grover, who gets excited over the candy corn Hecate left behind. As Nop continues spreading his incontinence everywhere, Annabeth reveals that Hecate’s library tempted her with dangerous books, reinforcing Percy’s theory that the goddess is testing them. They decide to use Nop as bait to lure Hecuba in Astoria, hoping her maternal instincts will work in their favor. However, there are no guarantees of success.

Chapter 14 Summary – Wrath of the Triple Goddess – We Find Some Dead People

In Astoria, Percy, Annabeth, Grover, and Nop search for Hecuba. The puppy leads them to Athens Square, a park decorated with Greek statues, including one of Athena. Annabeth jokes about her mother while Nop tugs on his leash toward a shadowy stain on the ground, possibly Hecuba’s trail. Suddenly, a terrifying howl breaks the silence, drawing them to a Greek restaurant where customers flee in panic, screaming about "giant rats!" When they arrive, they see Hecuba on the rooftop, reveling in the chaos while her resurrected Trojan soldiers attack. During the battle, Percy is touched by an undead warrior and is thrown into a vision of Troy in flames, reliving Hecuba’s agony over losing her children. When he regains consciousness, he vomits and feels weak. Annabeth deduces that Hecuba wants to share her suffering with the Greeks of New York. Before they can react, more screams echo through the city, forcing them to run toward the next threat.

Chapter 15 Summary – Wrath of the Triple Goddess – I Flunk Canine Diplomacy

Following the trail of destruction, they find Hecuba at Papou’s Pastry Shop, where an elderly Greek man is trying to fend off the undead Trojans with a broom. Annabeth, Grover, and Percy take down the invaders, though Annabeth is touched and left dazed. Grateful, Papou offers them baklava, but they decline and continue pursuing Hecuba onto a rooftop. There, the hellhound seems hesitant, drawn by Nop’s scent. Percy uses the puppy as bait, hoping to appeal to Hecuba’s maternal instincts. Grover translates her growls while Annabeth mimics a nurturing mother to provoke her jealousy. As Hecuba approaches, Percy attempts to leash her, but he isn’t subtle enough. Enraged, Hecuba leaps into the void, activating a portal of shadows. Still holding Nop, Percy is pulled into the swirling darkness, leaving Annabeth and Grover behind.

Chapter 16 Summary – Wrath of the Triple Goddess – Hellhounds in the Club

Percy is dragged through the shadows by Hecuba in a chaotic journey while holding Nop, who barks excitedly. When they emerge from the portal, they find themselves in a German nightclub, where the hellhound bursts onto the dance floor, causing a mix of surprise and enthusiasm among the patrons. However, she doesn’t linger long and soon whisks Percy away again, transporting them to a desert in Turkey near the ruins of Troy. Percy tries to calm Hecuba, reminding her that Hecate needs her. Finally, the hellhound stops at the shore, visibly moved by memories of her past. Percy speaks to her about the importance of family and manages to convince her to return to New York. Exhausted, he collapses upon arriving at the mansion, where Annabeth greets him warmly, celebrating his success.

Chapter 17 Summary – Wrath of the Triple Goddess – Grover Connects with Nature

Percy wakes up drained from his journey with Hecuba. Annabeth informs him that he must attend class, leaving him and Grover in charge of finding Gale, the missing ferret. Grover suggests "connecting with the earth" in Gramercy Park, a method that involves burying himself in the ground to receive information from animals and nature. As Percy watches, dozens of squirrels surround Grover, along with a massive rat named Eustis. After an intense trance, Grover wakes up and reveals that the only clue about Gale is her presence on Lafayette Street alongside "four spirits from beyond the coast." Percy and Grover decide to start their search in Manhattan, uncertain about the meaning of the cryptic message. Before they leave, Percy is unsettled when he discovers a pair of mysterious glasses in Hecate’s library, with initials that feel eerily familiar.

Chapter 18 Summary – Wrath of the Triple Goddess – I Smell Trouble™, a New Fragrance for Men

As they explore Lafayette Street, Percy and Grover notice an unusual concentration of perfume shops, reminding them that Gale, before becoming a ferret, was a witch skilled in potions and fragrances. They spot a Greek-themed perfume shop called EEA and decide to investigate. From the window, Percy senses the presence of a hostile naiad. When she sees him, the woman flies into a rage and attacks them, hurling perfume bottles. Percy and Grover try to defend themselves but end up getting sprayed with a strange potion. In desperation, Percy uses his powers to redirect the liquid back at the naiad, causing her to dissolve into a perfumed mist. However, the effort leaves him completely dehydrated, and he loses consciousness. When he wakes up, Grover gives him water and explains that they’ve been unconscious for an hour. They suspect that Gale is trapped in the perfume business and decide to continue their investigation.

Chapter 19 Summary – Wrath of the Triple Goddess – Oops! I Killed You Again

Percy and Grover enter EEA and speak with a disinterested clerk named Green Hair. He mentions that their rival perfume shop, Agua Fina, has a saleswoman named Silbe, who may be one of the sisters of Philomela, the naiad who attacked them. Green Hair also mentions a mysterious perfume called Miracle, which has been a bestseller since Tuesday—the same day Gale disappeared. Percy and Grover suspect that the perfume was made with Gale’s help and decide to investigate Agua Fina. Before leaving, Green Hair suggests that Philomela and Silbe are locked in a business rivalry and that Gale might be the key to their feud. Convinced that the mustelid is caught between the sisters, Percy and Grover prepare to enter the second perfume shop, fully aware that another magical attack may be waiting for them.

Chapter 20 Summary – Wrath of the Triple Goddess – We Get Dangerously Fine-Tuned

At Agua Fina, Percy and Grover pretend to be customers. Grover, posing as a perfume buyer for his girlfriend Juniper, manages to distract Silbe, who confirms that Miracle is just a cheap product made by her sister, Philomela. Percy notices the presence of another naiad in the shop, confirming their suspicions. When Silbe begins to grow suspicious, she attempts to spray Grover with a sample of her special fragrance, Enchanted, but at the last moment, she changes targets and sprays Percy directly in the face. The liquid paralyzes him, and Silbe kneels beside him with a triumphant smile, revealing that she remembers him well and is about to turn him into "nobody." Grover, horrified, stands frozen, unsure of how to save his friend as Percy lies helpless on the floor.

Chapter 21 Summary – Wrath of the Triple Goddess – Grover Leaves a Five-Hoof Review

Percy is paralyzed by Silbe’s enchanted perfume, "Enchanted," one of the naiad sisters who own perfume shops in Manhattan. While Grover tries to negotiate Percy’s release, Silbe reveals that she wants to impress her sisters by harnessing the power of Gale, the magical ferret. Percy gradually regains control of his body thanks to a mysterious remedy from Grover, who distracts Silbe by offering to feature her in a five-hoof review in the Ancient Hooved Elders Magazine. Using a moment of quick thinking, Percy manages to spray Silbe with her own perfume, leaving her paralyzed. Grover and Percy wrap her up like a gift before continuing their search for Gale. Just as they finish, Annabeth bursts into the shop and, seeing the scene, demands an explanation. Percy and Grover, still looking disheveled, try to justify the chaos they’ve gotten themselves into while Annabeth stares at them with disbelief and exhaustion.

Chapter 22 Summary – Wrath of the Triple Goddess – Annabeth Asks to See the Manager

Annabeth listens to Percy and Grover’s story, scolding them for their lack of planning. Upon learning of the connection to Circe’s island, she recalls that the naiad perfume shop owners were once servants of the sorceress. Now, they seek revenge for the destruction of their home. With a new strategy in mind, Annabeth decides they need disguises to confront the remaining sisters, Daedra and Phaedra. In a costume shop, Annabeth dresses as a Roman noble, while Percy and Grover take on the roles of gladiators. Uncomfortable in his retiarius outfit, Percy endures the cold as they follow the trail to the perfume shop Fragrances Forever. Annabeth, exuding authority, demands to see the managers, surprising everyone with her performance. The terrified employee rushes to fetch the twin sisters while Percy and Grover brace themselves, still unsure of Annabeth’s true plan.

Chapter 23 Summary – Wrath of the Triple Goddess – We Find the Lair of the Evil Perfume

Annabeth confronts Daedra and Phaedra, pretending to be an envoy of Hecate. The naiads, furious yet intimidated, try to justify themselves, but Annabeth corners them with her wit. To prove her power, she presents Hecate’s palace key, leaving them momentarily unsettled. Seeing no other choice, the twins agree to show them where Gale is being held. In the back room, the group discovers a laboratory where Gale is chained, forced to craft potions under the threat of being stung by bronze bees if she stops working. Percy and Grover are horrified to see her in such a state. Annabeth demands her release, but the naiads pick up on the desperation in her voice and realize the truth: Annabeth has lost Gale and needs to retrieve her to avoid failing Hecate. Seizing the advantage, Daedra and Phaedra decide that eliminating the demigods is the best way to earn the goddess’s favor. Without warning, they launch an attack.

Chapter 24 Summary – Wrath of the Triple Goddess – We Create a Nice and Organized Uproar

Percy counters the attack by manipulating the surrounding liquids, turning the potion against Phaedra and paralyzing her. Annabeth tries to restrain her, but Daedra transforms into a giant bear and hurls her against the wall. Enraged, Percy fights Daedra, slicing off one of her paws and forcing her to revert to her original form. Meanwhile, Grover attempts to free Gale but is swarmed by the bronze bees. Percy gets trapped in a pool of thick liquid that immobilizes his foot while Annabeth struggles against Daedra and Phaedra recovers. Thinking fast, Grover improvises a torch with a Bunsen burner to scare off the bees. In a last-ditch effort, Phaedra drinks another potion and unleashes a deadly attack called "Beast’s Breath." A cloud of white gas engulfs the trio, and though they manage to defeat the naiads, they quickly realize that something is very wrong with them.

Chapter 25 Summary – Wrath of the Triple Goddess – The Beast Breath Blues Have No Cure

The "Beast’s Breath" attack has a devastating effect on the group: Annabeth undergoes a partial transformation into an owl, Percy grows octopus tentacles in place of his arms, and Grover loses his goat legs, becoming fully human. Desperate, they search for a cure in the laboratory, but Phaedra taunts them, claiming there is no antidote. Meanwhile, the overturned cauldron continues to spill corrosive liquid, threatening to bring down the entire building. Percy, realizing that Annabeth is unable to think clearly and that Grover is in shock, makes a difficult decision: he orders his friends to evacuate with their captured enemies while he stays behind. His plan is risky but his only option—he must talk to Gale and trust that the ferret, with her knowledge of magic, can help them reverse the transformation before it’s too late.

Chapter 26 Summary – Wrath of the Triple Goddess – Okay, There Might Be a Cure, But You Won’t Like It

Percy negotiates with Gale, Hecate’s ferret, while the laboratory collapses around them. Despite his half-octopus transformation, he manages to communicate with her and persuade her to help create an antidote. Initially hesitant, Gale agrees after a memory exchange in which Percy glimpses her tragic past as a witch rejected by humanity. Together, they prepare a potion amidst the chaos, but they only manage to create three doses. Before escaping the crumbling building, Percy breaks Gale’s chain, granting her the freedom she was denied for centuries. The explosion of the perfume shop seals their escape, and as the defeated naiads swear vengeance, Percy and his friends flee with the antidote—though they have no idea if it will work or just be another magical disaster.

Chapter 27 Summary – Wrath of the Triple Goddess – We Eat Toothpaste

Percy, Annabeth, and Grover take refuge in an alley and debate how to use the potion. Determined, Grover takes the first dose and experiences immediate side effects—intense vomiting—before finally regaining his goat legs. Annabeth, reluctant but resolute, drinks the second dose. For a moment, she appears to be choking, but then returns to her normal human form. Percy, however, faces a dilemma: only one dose remains, and Gale has the chance to regain her humanity. In an unexpected twist, the ferret refuses to become human again, preferring her immortal form and asking Percy to fulfill his promise of getting her a laboratory of her own. Grateful, Percy takes the final dose, endures its side effects, and finally returns to normal. Feeling victorious, they return to Hecate’s mansion with Gale, ready to face the next challenge.

Chapter 28 Summary – Wrath of the Triple Goddess – I Come Up with a Bad Plan

Back at the mansion, Percy and his friends try to enjoy a pizza dinner while assessing the extent of the damage. Grover feels guilty for the destruction, but Annabeth and Percy assure him that they’ll find a solution. Percy suggests using Hecate’s magical torches to summon ghostly builders, though he knows the idea is risky. Annabeth, initially skeptical, considers the possibility, recalling her vision of Troy’s fall and her connection to architecture. They decide to consult Gale about a potion to protect them from the dead, but the process will take all of the next day. While Annabeth and Percy prepare for their exams, Grover offers to keep watch over the mansion. Still uneasy, Percy meets Annabeth outside, and they share their concerns about the mansion’s curse, convinced that they must uncover its past before attempting to restore it.

Chapter 29 Summary – Wrath of the Triple Goddess – I Take All the Candy

Percy visits his mother at the Cracked Teapot and tells her about his mission. Though worried, Sally expresses her confidence in him and reminds him to support Annabeth no matter what. Percy also asks about the vision of the girl with broken glasses, learning that it was actually his mother as a child—who once saw Hecate’s mansion and was warned by the goddess to stay away. Reflecting on Hecate’s choices, Percy realizes that the goddess may be trapped by her own regrets. He then visits Eudora, his school counselor, who confesses that she was once part of Hecate’s failed school of magic in 1914. Eudora reveals that the school closed due to internal conflicts during World War I and that Hecate has resented her ever since. Armed with new information about the mansion’s history and the goddess’s past, Percy resolves to fix the situation—and leaves with an entire jar of lucky candies.

Chapter 30 Summary – Wrath of the Triple Goddess – We Get Ourselves Ready for Battle

At nightfall, Percy returns to the mansion, where Annabeth and Grover have already devised a plan to summon the dead. They decide to visit St. Mark’s Cemetery and awaken the spirit of Peter Stuyvesant, the former governor and builder of New Amsterdam, hoping he will help restore the mansion. Gale has prepared a protective ointment against ghosts, and Hecuba and Nop will accompany them to guide the souls. Percy shares what he learned about Hecate and her failed magic school, confirming that the mansion has been in decay since its closure. Annabeth realizes that unless they resolve the house’s past, any restoration will be superficial. Armed with the magical torches, the group prepares for their dangerous mission. As Percy holds the torches, he jokes about his questionable ability to focus, but everyone knows that what happens next will determine whether their quest succeeds or fails.

Chapter 31 Summary – Wrath of the Triple Goddess – We Find More Dead People

Percy, Annabeth, and Grover arrive at St. Mark’s Church at night, a place seemingly cut off from the world. They sneak into the cemetery, where ancient graves lie hidden beneath brick pathways, and a thick mist covers the ground. Annabeth lights the torches with magic, summoning spirits to rebuild Hecate’s mansion. The first to appear is Peter Stuyvesant, a smoky shadow with a peg leg, followed by a host of angry specters awakened by the invocation. Though Annabeth struggles to control them, the ghosts are hostile, bitter about being forgotten by the city. Tension rises when Stuyvesant, intrigued, agrees to follow Annabeth—but only to test her. As the ghostly army surrounds them, Percy, overwhelmed by the spectral energy, fears they’ve awakened forces beyond their control.

Chapter 32 Summary – Wrath of the Triple Goddess – We Totally Nail the Torch Handoff

Leading the ghosts, Annabeth stumbles after barely a block. The strain of controlling the dead is exhausting her, and Percy decides to take the torches to ease her burden. Despite Hecuba’s warning about the dangers of transferring them, Percy insists, and Annabeth relents, collapsing into Grover’s arms. With the torches in his grasp, Percy feels the crushing weight of spectral energy and struggles to maintain control. As they march forward, more ghosts join them, and Stuyvesant watches with amusement, waiting for Percy to falter. With tremendous effort, Percy presses on until they reach Hecate’s mansion in Gramercy Park. Annabeth, still weak, joins him on the porch, and together, they hold the torches high. With a final command, they order the spirits to rebuild the mansion, hoping their task will be completed before the magic consumes them.

Chapter 33 Summary – Wrath of the Triple Goddess – We Celebrate a Classic Witch Burning

The mansion’s restoration is complete, but instead of vanishing, the ghosts remain, their presence growing more menacing. Annabeth attempts to banish them by crossing the torches, but it doesn’t work. Percy, exhausted, collapses and nearly drops one of the torches, almost triggering disaster. Grover helps revive them with divine nectar, buying them a moment to recover. However, Stuyvesant reveals his true intent: to burn Hecate’s house to the ground and eradicate her followers. The ghosts attack furiously, and Percy and Annabeth barely manage to fend them off with the torches. Gale provides jars of protective ointments, but the horde of spirits keeps growing. Suddenly, Stuyvesant becomes more powerful, joined by ghosts in Halloween costumes and possessed mortals, including a police officer with a pumpkin for a head. Realizing that Stuyvesant is Hecate’s son, Percy understands that his hatred is personal. Their enemy has gathered an army, and the battle is just beginning.

Chapter 34 Summary – Wrath of the Triple Goddess – We Fight for Hecate and Also for Fish

A brutal battle erupts against the ghosts and possessed mortals. Percy slashes through the spectral attackers, but they regenerate endlessly. Grover plays his flute to lure the possessed away, while Annabeth defends the mansion’s entrance with the torches. Hecuba and Nop fight fiercely, taking down enemies with bites and tackles. Amid the chaos, Hecate’s eels unexpectedly emerge from their tank, soaring through the air like aquatic projectiles and attacking the ghosts. Percy, growing weaker, tries to face Stuyvesant but is overwhelmed. Every strike from the ghosts drains him further, drowning him in visions of past deaths. Stuyvesant knocks Percy down, leaving him vulnerable for a final blow. Without strength or weapons, Percy braces for the end when, suddenly, an unexpected sound interrupts the battle, offering him a final chance to survive.

Chapter 35 Summary – Wrath of the Triple Goddess – My Idiocy Saves Me

Just as Stuyvesant’s spectral horse is about to trample Percy, a blaring car horn echoes through the street. The Delphi Strawberries van arrives, carrying demigods dressed for a Halloween party, unaware they’ve stumbled into a battle. Connor Stoll and other campers charge into the fray, using their unique skills to drive back the ghosts. Clovis puts the possessed to sleep, Valentina lassos them with her pearl necklaces, and Harley rushes in with his celestial bronze armor. Argus, the camp’s many-eyed security guard, lifts Stuyvesant’s horse off the ground, neutralizing the threat. Percy rushes to Annabeth, who is on the brink of collapse, and together, they cross the torches one last time. A burst of light engulfs the ghosts, dissolving Stuyvesant. Clovis offers him eternal rest, and the battle ends. Exhausted but victorious, the demigods celebrate as Connor suggests they continue the party.

Chapter 36 Summary – Wrath of the Triple Goddess – I Skip the Celebration

The Halloween party at the mansion is a success. Austin Lake from the Apollo cabin plays music, while Connor Stoll handles the snacks—likely stolen from camp. Satyrs and nymphs dance nonstop, and Hecuba and Gale enjoy the company. Percy regrets that Mrs. O’Leary couldn’t attend but consoles himself with the thought of seeing her soon in California. The party goes smoothly until Valentina Diaz, dressed as Coco Chanel, accidentally breaks a lamp with her pearl necklaces, though Harley quickly fixes it. Later, Percy finds Annabeth on the terrace, where they discuss their fatal flaw: pride. He reassures her that they make a good team because they balance each other’s weaknesses.

Chapter 37 Summary – Wrath of the Triple Goddess – I Play with Purple Fire

Hecate returns to the mansion at 5:32 a.m., stepping through a fire portal from Grand Central. Her outfit is covered in confetti and candy, and her three heads wear strange accessories, including a Richard Nixon mask. Upon noticing Nop, she’s surprised to learn that Hecuba has adopted him. When Percy tries to speak with her, the goddess is distracted until she spots a plastic bottle in the room, pretends to be furious, and incinerates it with purple flames. Finally, she hands Percy his recommendation letter—a simple parchment endorsing him for "things." Instead of leaving with his prize, Percy confronts her, telling the whole truth about the week: the strawberry milkshake disaster, the battle with Stuyvesant, and the needs of her pets. Hecate, though initially indignant at his boldness, is taken aback by his honesty. Percy asks her to grant Gale a laboratory, give Hecuba more freedom, and reopen the magic school. After a tense moment, Hecate smiles and agrees to consider his request, admitting that Percy has impressed her.

Once she reconstitutes herself, she thanks him effusively, dancing around her office in euphoria over her new opportunity as the school’s admissions director.

As Sally works on her novel, Percy recounts everything that happened. She congratulates him for leaving things better than he found them and reminds him how proud she is of him. Percy, deeply moved, can barely respond. Before he leaves, Sally asks him to do the laundry and clean the living room, reminding him that being a hero doesn’t exempt him from chores.

FAQs – Chapter by Chapter Summary – Wrath of the Triple Goddess

What role does Hecate play in “Wrath of the Triple Goddess”?

Hecate is not just the one who sets the story in motion with a “harmless” pet-sitting mission — she’s the emotional and magical heart of the book. Her hidden past, magical legacy, and conflicted motivations weave through every chapter. She tests the characters, manipulates the setting, and ultimately reveals her own vulnerability. Far from being just another god cameo, she’s a deeply flawed and compelling figure whose choices shape the entire emotional arc of the story.

Why is the hellhound puppy Nope important to the story?

Nope adds more than comic relief — he’s a symbol of empathy and second chances. His bond with Percy provides grounding amidst the chaos, and his innocent yet fierce loyalty brings out the best in everyone. Nope is key to reuniting with Hecuba, and later becomes instrumental in calming tensions and anchoring characters in moments of despair. He reminds the reader that even in magical mayhem, small creatures can have massive emotional impact.

What secrets does the mansion in Gramercy Park hide?

Hecate’s mansion is not just a backdrop — it’s a haunted monument to a failed magical experiment. We learn that it used to be a school for witches, abruptly shut down in 1914 after internal betrayal and war. That collapse left emotional scars on Hecate and her former students. The mansion's spectral legacy affects the living, the dead, and even the architecture itself. Uncovering its past is essential to healing its future.

Why do perfume shops matter so much in the plot?

The perfume shops are more than quirky settings—they're battlegrounds. Run by vengeful naiads once allied with Circe, they are magical fronts for power struggles and personal revenge. The enchanted fragrances serve as weapons, traps, and clues, and become central to uncovering Gale’s fate. The idea that scent can dominate will and memory makes the perfume subplot both sinister and elegant, transforming beauty into danger.

How does the final battle unfold and what is its resolution?

The climax involves a ghost army led by Hecate’s vengeful son, Peter Stuyvesant, who wants to burn her legacy down. Percy and Annabeth use the goddess’s torches to rally spirits and fight back, but things spiral when the ghosts remain after rebuilding the mansion. The final stand forces Percy and Annabeth to cross the torches one last time, unleashing purifying light that dissolves the spirits. It’s a resolution built on risk, sacrifice, and insight — not brute force.
