Introduction – The Blood of Olympus

Blood doesn’t always flow through veins—it seeps into ancient vows, broken prophecies, and wounds that refuse to heal. In The Blood of Olympus, Rick Riordan concludes his saga with a ticking clock toward the end of the world, where demigods must choose between loyalty and loss, between the past that shaped them and the future they barely understand.

The conflict between Greeks and Romans intensifies as Gaia rises, ready to obliterate everything touched by hope.

Each chapter is a threshold between prophecy and blood, a climb toward an inevitable climax. But if you want to understand where every alliance, betrayal, and scar began, the real journey starts much earlier. Reading order of The Heroes of Olympus ➤

Chapter 1 Summary – The Blood of Olympus – The Infiltration in Ithaca

Jason, Piper, and Annabeth climb a hill in Ithaca disguised as Greek pilgrims, hidden by Hazel’s magic. Jason undergoes a temporary transformation into an old man, weakening him as he observes the island and the Argo II anchored in the bay. Their mission is to infiltrate Odysseus’ ancient palace, where an army of evil spirits has gathered under Gaia’s command. Jason recalls Hazel’s warning about the dangerous concentration of souls in the area. As they advance, Jason’s thoughts are disturbed by recent nightmares about Juno and his mother, Beryl Grace. Upon reaching the summit, a loud explosion echoes through the air, followed by the cheers of the ghosts. The crowd seems to be celebrating a macabre spectacle, confirming that their mission will be even more dangerous than expected. Jason and his friends prepare to infiltrate the horde of the undead.

Chapter 2 Summary – The Blood of Olympus – The Feast of the Dead

Jason watches in horror at the ruins of Odysseus’ palace, where hundreds of ghosts and demons revel in a gruesome feast. Antinous, the leader of the resurrected suitors, destroys a statue of Zeus in a fountain of golden sand as an offering to Gaia. Concealed by the Mist, Jason disguises himself as Iros, an old beggar of the palace, and approaches Antinous. Pretending loyalty, he sits with the spirits and learns that they plan to ambush the demigods upon their arrival in Ithaca. Moreover, Gaia has deployed forces to block the Corinth Canal, forcing the Argo II to take the dangerous route around the Peloponnese. Just as Jason believes he has gathered enough information to retreat, Michael Varus, a deceased Roman praetor, recognizes and confronts him. Before Jason can react, Varus reveals that someone has come specifically to seek him out, and to his shock, the specter of his mother appears before his eyes.

Chapter 3 Summary – The Blood of Olympus – Jason’s Ghost from the Past

Jason is paralyzed at the sight of his mother’s spirit, Beryl Grace, who begs him to join the suitors. Piper and Annabeth try to snap him out of his trance, but his mother’s influence consumes him. Michael Varus taunts Jason, telling him he will never find a home or be accepted by either the Greeks or the Romans. Jason recalls his childhood and the abandonment by his mother, finally rejecting her offer. With a gesture of protection against evil, he destroys her image, freeing himself from her influence. Furious, Antinous orders his death, and ghosts and demons surround Jason and his friends. At that moment, Piper uses her persuasion abilities to sow distrust among the suitors, inciting chaos. As tension reaches its peak, Jason, Annabeth, and Piper prepare for battle, knowing that their only option is to fight their way out and escape alive.

Chapter 4 Summary – The Blood of Olympus – The Battle at Odysseus’ Palace

Jason and his friends fight fiercely against the suitors and demons. Jason strikes down Antinous with his javelin, reducing him to dust. Annabeth battles skillfully, while Piper uses her cornucopia to launch food at their enemies and distract them. Jason summons a lightning bolt that obliterates several ghosts. For the first time in a long while, he feels in control and confident in who he is. However, just when he believes the battle is won, Michael Varus stabs him in the back with his imperial gold gladius. Jason falls to his knees, gravely wounded. Piper and Annabeth rush to his aid, binding his wound and feeding him ambrosia, but the injury continues to smolder, affecting him beyond the physical realm. As Piper orders him to stay conscious, Annabeth signals the Argo II for help using a mirror. Weakened, Jason recalls the story of Odysseus and Penelope’s wedding bed and, with his last breath, calls upon Juno’s name.

Chapter 5 Summary – The Blood of Olympus – Reyna and Nico’s Escape

Reyna, Nico, and Coach Hedge emerge from shadow travel and plummet toward Mount Vesuvius. Exhausted, Nico cannot transport them again, but Reyna uses her power to strengthen him, allowing him to save them just before they crash into the volcano. They appear in the ruins of Pompeii, next to the Athena Parthenos. Reyna feels the extreme toll Nico is enduring from sharing his burden of pain. Nico warns them about the lemures, hostile ghosts of the city. As he collapses from exhaustion, Reyna commands the metallic dogs, Aurum and Argentum, to stand guard. She reflects on Nico’s bravery and their mission, feeling growing respect for him. Despite the tension, Coach Hedge jokes about his new “Satyr’s Home,” momentarily easing the atmosphere. With the statue secured, Reyna lies down beside her companions, fully aware that the journey ahead will only grow more difficult.

Chapter 6 Summary – The Blood of Olympus – Nightmare in Bacchus’ Garden

Reyna tries to control her nightmares by retreating to her favorite garden in New Rome, but a terrifying vision overwhelms her. She sees a wave of dark mud sweeping through Camp Jupiter, destroying everything in its path. Terminus attempts to hold back the tide, but it is futile. Amid the devastation, a female voice accuses her of leaving her home defenseless. Then, a hunter with glowing eyes shoots an Stygian iron arrow at her. Before the dream shifts, Reyna finds herself in a warehouse on Long Island, where Octavian has set up his camp. She watches as he recruits Bryce Lawrence, a former legionnaire expelled for cruelty. Octavian, growing more ambitious, plans an attack on Camp Half-Blood. Reyna abruptly wakes up when Hedge shakes her; his worried tone suggests imminent danger, but what he fears is not monsters or ghosts—it is tourists.

Chapter 7 Summary – The Blood of Olympus – The Ghosts of Pompeii

Reyna, Hedge, and Nico hide among the ruins of Pompeii, where the Athena Parthenos statue draws the attention of wandering spirits. As she watches the tourists, Reyna cannot shake her nightmare of Camp Jupiter’s destruction. The vision of Octavian manipulating the legion fills her with helplessness. She steps away from the group to use the facilities and stops in front of a museum displaying plaster figures of Pompeii’s ancient inhabitants. A shiver runs down her spine as she imagines their suffering, wondering if Rome’s legacy is also doomed to disappear. When she returns, the afternoon passes in tense silence. When Nico wakes, Reyna shares her dreams, and he suspects that the hunter in her vision could be a giant. They decide to send a message to Thalia and Hylla for help. However, before they can leave, the ground trembles, and Hedge, now speaking with Gaia’s voice, warns them that they will die in Pompeii.

Chapter 8 Summary – The Blood of Olympus – The Attack of the Mud Ghosts

Reyna and her companions are attacked by Pompeii’s ghosts, whom Gaia has granted bodies of stone and ash. While Nico attempts to prepare a shadow jump, Reyna orders him to summon Roman legionnaires with Diocletian’s scepter. Despite his hesitation, Nico succeeds, and skeletal soldiers reinforce their defense. Reyna leads the battle, fighting alongside the dead as her mechanical dogs guard the Athena Parthenos. However, Diocletian’s scepter cracks, and the spectral soldiers begin to fade. As the situation turns dire, Nico finally opens a portal in the shadows. Just as Reyna tries to reach it, a blow from the mud ghosts knocks her to the ground, leaving her breathless. Voices in her mind try to convince her that Rome is lost, but she refuses to surrender. With the last of her strength, she leaps into the darkness, trusting Nico to get them out.

Chapter 9 Summary – The Blood of Olympus – Leo and His Secret Project

Leo hides inside the Argo II, working on a series of secret modifications to the ship. Piper interrupts him for a meeting, but before leaving, he checks his drawer, where he keeps two valuable objects: an astrolabe from Archimedes and a crystal from Ogygia. He has not yet managed to combine them, which frustrates him. In his cabin, he gazes at a portrait of Calypso, remembering his promise to return for her. When he arrives at the dining area, he watches his friends interact in pairs and feels like the seventh wheel. The crew discusses their next mission: subduing Nike, the goddess of victory. They suspect that her dual nature, divided between Greek and Roman aspects, is intensifying the rivalry between the two camps. Frank suggests a team of four for the mission—Leo and Percy for the Greeks, and Frank and Hazel for the Romans. Before departing, Leo grins at the challenge of defeating victory itself and heads off to prepare his explosives.

Chapter 10 Summary – The Blood of Olympus – The Encounter with Nike

Leo and Percy explore the Olympia museum while Frank and Hazel scout the ruins. Leo feels uneasy around Percy, remembering that they both share a connection to Calypso. Just as he tries to bring up the topic, Frank interrupts them. They regroup and share information—the ruins are vast, and they have found no sign of Nike. As they walk through the site, Frank explains the monuments while Leo jokes about the amount of rubble. However, as they progress, Leo grows increasingly uneasy, sensing that they are awakening something dangerous. They stop in front of the ruins of Zeus’ temple, and Leo connects the destroyed Nike statue in the museum to the temple itself. At that moment, a thunderous voice confirms his suspicions. Riding a golden chariot, Nike appears before them, ready for battle.

Chapter 11 Summary – The Blood of Olympus – Nike’s Challenge

Leo, Percy, Frank, and Hazel face the goddess Nike in Greek ruins. Divided between her Greek and Roman aspects, she demands a battle to determine the victor, further fueling tension among the demigods. Despite the pressure, the group refuses to fight each other, enraging Nike. The goddess summons her metallic warriors, the Niketas, and forces the heroes to run toward an ancient Olympic stadium. There, Hazel uses her magic to alter the battlefield with illusions and traps, while Leo and Percy deploy Archimedes’ devices. Percy slices through a Niketa with Riptide, Frank defeats another by transforming into a bear, and Hazel neutralizes the third. When Nike charges at them with her chariot, Leo tricks her with a fake lightning bolt of victory and captures her in a celestial bronze net. Although the goddess warns that one of them will die on their mission, the group locks her in the Argo II and prepares to search for the physician’s cure.

Chapter 12 Summary – The Blood of Olympus – Deadly Games in Olympia

While Hazel distorts the battlefield with the Mist, Leo and Percy detonate explosives to simulate a battle between Greeks and Romans, deceiving Nike. Frank pretends to attack them with his bow but is actually aiming at the Niketas. One falls after being ambushed by Percy, who cuts it in half. Hazel manipulates the labyrinth to isolate the others, allowing Frank—transformed into a bear—to crush a second one. However, Nike, furious at the trick, orders her remaining Niketas to attack more aggressively. Percy, Leo, and Hazel fight as Frank fires flaming arrows to distract the goddess. Finally, Percy uses a water geyser to overturn Nike’s chariot, allowing Leo to capture her with Archimedes’ net. The goddess is trapped, cursing them and warning that victory will come at the cost of blood.

Chapter 13 Summary – The Blood of Olympus – The Message from the Dreams

Nico falls unconscious after an exhausting shadow jump. In his dream, he revisits painful memories before encountering Clovis from the Hypnos cabin. Clovis confirms that Camp Half-Blood is surrounded by Octavian’s forces and that the Greeks are divided on whether to resist or attack. Nico asks him to warn Thalia, suspecting that a giant of Gaia is hunting them. Then, his vision shifts, and he witnesses a meeting at camp. Clarisse suggests a preemptive strike, but the other counselors prefer to wait for the Athena Parthenos. Rachel and Will Solace explain that Apollo’s powers are blocked, preventing them from seeing the future. As Clarisse and Malcolm argue over strategy, Connor Stoll defends Annabeth’s mission, arguing that her message from Tartarus proves that her plan is their best hope. Before waking up, Nico hears Coach Hedge’s voice warning of trouble.

Chapter 14 Summary – The Blood of Olympus – Meeting in the Chapel of Bones

Nico wakes up in Évora, Portugal, alongside Reyna and Coach Hedge. He learns that he has been unconscious for thirty-six hours and that the Athena Parthenos remains stranded atop a temple. As they attempt to recover, Hedge points out the presence of a ghostly figure engulfed in flames. Nico follows it and is guided to the Chapel of Bones, where he encounters his father, Hades. The god warns him that Orion, a giant hunter loyal to Gaia, is tracking them and that they will find no rest until they reach Camp Half-Blood. He also mentions that Hazel has discovered one of the Seven will die but reminds Nico that some deaths are inevitable. Before vanishing, Hades expresses his respect for his son and tells him that he hopes he finds happiness. Confused and troubled, Nico returns to his companions, aware that danger is drawing closer.

Chapter 15 Summary – The Blood of Olympus – Orion’s Wolves

As they have dinner, Nico shares Hades’ warning about Orion and his wolves with Reyna and Hedge. Reyna wonders if the wolves could have been sent by Lupa, but the possibility seems unlikely. Nico, exhausted from shadow travel, knows they must move soon. When Hedge mentions the difficulty of lowering the statue from the temple, Reyna’s metal dogs tense up. Seconds later, a pack of black wolves leaps from the rooftops, surrounding their camp. One of them transforms into a tall, cadaverous man with red eyes and a crown of bones on his head. With a cruel smile, he declares that Hedge’s wish has come true—they will remain in Évora forever because his “metaphorical” wolves are, in fact, very real.

Chapter 16 Summary – The Blood of Olympus – Lycaon’s Attack

Nico, Reyna, and Hedge are surrounded by Lycaon and his pack of wolves in Évora. The king of the werewolves mocks Reyna and warns her that Orion will soon arrive to finish them off. As the wolves tighten the circle, Nico devises a plan: Hedge climbs up to the Athena Parthenos to throw down a rope, while Reyna and her dogs defend them. Nico uses his power to summon a wall of bones from the ancient dead of the city, trapping most of the wolves, but Lycaon manages to break free. At the last moment, Nico stabs him with Reyna’s silver dagger, causing the werewolf to dissolve into shadows. Just as the remaining wolves lunge at them, a voice commands them to stop, and the sound of a bowstring being drawn echoes from a rooftop. Nico seizes the opportunity, using Lycaon’s shadow to teleport with his friends and the statue—without knowing where they will appear.

Piper and Frank search for poison in Pylos and encounter monsters along the way. After receiving information from a ghost in a laundromat, they arrive at Nestor’s cave, where Frank finds his shapeshifter relatives, descendants of Periclymenus. Though distant, they give him Pylos mint, a rare poison, and explain that they must go to Sparta to free the chained god—Ares. Piper and Frank return to the Argo II, where Leo suggests they depart immediately. During a meeting on the deck, they discuss the mission and how Ares’ heartbeat could help them locate the cure. Jason suggests heading to Sparta as soon as possible, and Annabeth recalls Piper’s vision, where they stood among ruins with a bronze statue surrounded by flames.

As she sleeps, Piper has a vision of the Acropolis in Athens, where Porphyrion and the giants prepare for Gaia’s awakening. She discovers that a giant named Thoas is destined to destroy the Fates and that the demigods will be sacrificed there. The vision is interrupted when Annabeth wakes her—they have arrived in Sparta. Troubled by her dream, Piper shares the information with her friends before setting out.

Annabeth and Piper explore Sparta in search of the chained god. They search the city without success until they find three pits that randomly burst into flames. Piper feels a connection to them and, following her intuition, jumps into one. She lands in an underground chamber where a statue of Ares is chained, surrounded by three fire-breathing bronze dragons. Annabeth follows, and together they destroy the dragons. As they examine the room, they discover inscriptions about Phobos and Deimos, the gods of fear and panic. Suddenly, the giant Mimas appears, taunting them before attacking with his war hammer. Annabeth is paralyzed by fear, but Piper snaps her out of the trance and drags her into a dark tunnel to escape.

Chapter 20 Summary – The Blood of Olympus – The Spirits of Battle

Piper and Annabeth flee from Mimas through a tunnel where the darkness amplifies their fears. Piper tells Annabeth that she cannot escape her emotions with logic—she must accept them. When they return to the main chamber, they attack the giant and wound him, but Mimas regenerates. Piper realizes that the statue of Ares is binding the makhai, the spirits of battle, and must be freed. She offers her cornucopia as a sacrifice and cuts off the statue’s head. A whirlwind of fire engulfs Piper, filling her with the makhai’s energy, and they promise to aid her when summoned. With one final attack, Annabeth and Piper make Mimas stumble and get crushed by a massive rock. As the temple collapses, they leap through the Gate of Fear, hoping it will take them to the surface.

Nico, exhausted, collapses, and Reyna struggles with the overwhelming feeling of being back home—the place she fears most. As unease consumes her, she tries to focus on pleasant memories of the city, but the dread of facing her past is stronger. While investigating the surroundings, she notices movement on the balconies. Before she can react, a needle pierces her neck, leaving her paralyzed. Her dogs collapse, as does Hedge. Figures dressed in gray surround her and take her captive.

After a tense confrontation, Thalia explains that they had no intention of harming her but intercepted her for her safety. They take her to an Amazon shelter, where they explain that they have been battling Orion, a formidable enemy hunting them. Reyna demands to see her sister, Hylla, who has been awaiting her arrival. As Thalia leaves to monitor the defenses, Reyna is escorted into the Amazon warehouse. Upon seeing her, Hylla greets her with irony, warning that once again, they find themselves in a life-or-death situation.

Chapter 23 Summary – The Blood of Olympus – The Plan to Defeat Orion

Reyna and Hylla reunite, but tension lingers between them. The Amazon queen explains that they intercepted Reyna because Orion is hunting her. The giant has been an enemy of the Hunters and Amazons for centuries, obsessed with destroying strong women. Phoebe, a Hunter, recounts how Orion was rejected by Artemis and has sought vengeance ever since. Reyna deduces that they have used her presence as bait to lure him in. Hylla confirms they have set a trap, with their best warriors waiting for the right moment. Reyna feels used but decides to cooperate. In return, the Amazons repair her mechanical dogs and provide her with supplies. However, just as they finalize their plan, an Amazon bursts in with urgent news—the outer defenses have gone silent. Orion has arrived. Before they can react, the gates explode, and the enemy storms into the warehouse.

Hylla has reclaimed the property, confronting the ghosts of their past. But there is no time to dwell on memories, as Orion finds them. Reyna stands her ground, refusing to fall for his provocations. The giant mocks her struggle, assuring her that she will never find a place where she belongs. Before he can strike, Reyna and Hylla charge together, determined to fight to the end. Just as all seems lost, Nico, Hedge, and the Hunters arrive, launching an explosion of Greek fire. Hylla shouts for Reyna to run. She obeys, but the voices of her past haunt her.

Jason wakes up in the middle of a violent storm. Despite his weakness, he decides to help the crew. Percy is using his power to keep the waves from destroying the ship but tells Jason that something else is causing the chaos. Without hesitation, Jason summons a ventus and dives into the ocean alongside Percy. Underwater, they find a ruined palace illuminated by eerie green flashes. Inside, a gigantic woman manipulates a strange metal disc, generating the storm. When Jason confronts her, she responds with a melodious but unsettling voice. She introduces herself as his sister and warns him that she wanted to meet him before killing him.

Chapter 26 Summary – The Blood of Olympus – The Deal with Kymopoleia

Jason and Percy find themselves trapped in the ruins of Poseidon’s ancient palace, held captive by Kymopoleia, goddess of violent storms. Resentful toward the gods, she has allied with Gaia and unleashes a tempest that threatens to destroy the Argo II. When Jason attempts to negotiate, the goddess expresses her disdain for Romans and her thirst for revenge. However, Jason offers her recognition at both Camp Jupiter and Camp Half-Blood, promising temples in her honor. Meanwhile, Polibotes, Poseidon’s enemy giant, arrives with venomous basilisk minions that attack Percy. Jason, wielding his command over wind and electricity, electrocutes the serpents. Percy, weakened by the giant’s poison, is ensnared in a net. Jason convinces Kymopoleia that Gaia is merely using her, persuading the goddess to turn against Polibotes. Together, they defeat the giant, decapitating him with her bronze disc.

Chapter 27 Summary – The Blood of Olympus – The Poison of Polibotes

With Polibotes defeated, Percy remains trapped in the net, weakened by the poison. Desperate, Jason uses his ventus to provide him with air and help him expel the toxins. Pleased with the victory, Kymopoleia reminds Jason of his promise and demands that he uphold his word to grant her recognition among demigods. As Percy recovers, he jokingly remarks about Jason offering to make a doll in her honor. Before departing, the goddess warns Percy that his fate is tied to Gaia’s awakening and that his blood will be crucial to her return. She also mentions that Hazel has impressed the sea spirits, who are fighting to protect Long Island. Jason asks how they can defeat Gaia, and Kymopoleia suggests they follow the example of the Titans when they overthrew Uranus. Troubled by what this implies, Percy and Jason decide to return to the Argo II before they run out of oxygen.

Chapter 28 Summary – The Blood of Olympus – Jason’s Oath

As Percy recovers, Jason reflects on Kymopoleia’s warning. He recalls the prophecy about the fall of the world and wonders if his destiny is tied to Gaia’s defeat.

Jason jokes about being called Pontifex and realizes that his wound has completely healed, as if his decision to honor all gods has cleared his path. Percy asks if he truly intends to build temples for all minor gods, and Jason confirms that it is now his mission. He admits that he finally understands his role among the demigods and is determined to unite Greeks and Romans. Finally, both friends ascend to the surface to check on the Argo II and prepare for their next destination—Delos, in search of Apollo and Artemis.

Upon returning to camp, they find the Athena Parthenos hidden beneath a camouflage net. Reyna, deep in thought, observes a monument commemorating the Battle of Waxhaws, where British soldiers massacred surrendering colonists. She confesses that her family, the Ramírez-Arellanos, have served Bellona for centuries—some as heroes, others as villains. She mentions an ancestor who was a pirate and an uncle who was a commander in World War II. Then, she reveals her darkest secret: her father, a former soldier, became obsessed with Bellona’s visions and lost his mind, turning into a vengeful spirit. One day, he attacked Hylla, and Reyna killed him with an imperial gold saber. She believes her crime is unforgivable in Rome, as patricide is the worst sin. Before they can continue talking, Bryce Lawrence, a soldier of Octavian, appears.

Chapter 30 Summary – The Blood of Olympus – Nico’s Wrath

Bryce Lawrence, a descendant of Orcus, presents himself before Reyna and accuses her of patricide, threatening to take her to Octavian for execution. Hedge attempts to attack, but Bryce summons an army of spartoi—skeletal warriors condemned for breaking their oaths of clemency at the Battle of Waxhaws. Nico tries to command them, but they do not respond to his power. The skeletons capture Reyna and the satyr, leaving Nico feeling weakened and on the verge of fading. Bryce revels in the moment, revealing that Octavian has designed powerful war machines that will be used against Camp Half-Blood on August 1st. When Bryce injures Reyna and threatens to expose her secret, Nico’s fury completely unleashes. Darkness engulfs him, and his power manifests with terrifying intensity, setting the stage for his vengeance.

Chapter 31 Summary – The Blood of Olympus – Nico’s Power Unleashed

Nico loses control after Bryce Lawrence’s threat, unleashing a wave of cold and darkness that terrifies everyone. His fury forces Bryce to relive his most painful memories, pushing him to the brink of madness. Without mercy, Nico condemns him to a fate worse than death, turning him into a spirit without memory before the earth swallows him. Reyna and Coach Hedge are shocked by the display of power. Exhausted, Nico collapses and has disorienting dreams of Bianca, Hazel, Mellie, and Aclis, who seem to warn him of Gaia’s imminent awakening. When he wakes, he finds that he has been treated with a strange remedy from Hedge and had been on the verge of vanishing. Reyna informs him that three days have passed since his collapse and that he needs to regain his strength before hearing the bad news about their mission.

Chapter 32 Summary – The Blood of Olympus – Trust and New Alliances

After three days unconscious, Nico is surprised to learn that Reyna and Hedge stayed by his side instead of continuing the mission alone. Though initially fearful of his power, Reyna admits that she trusts him, as sharing her secrets has freed her from a heavy burden.

As they discuss their options, Hedge reveals that he has secured help to transport the Athena Parthenos. Suddenly, they see a group of pegasi approaching, led by none other than Pegasus, the lord of winged horses, who has answered their call for aid. With newfound hope, Nico, Reyna, and Hedge prepare for the next stage of their journey, believing they still have a chance to fulfill their mission before it is too late.

However, they must press on with their mission, and Leo insists on visiting Delos to speak with Apollo and Artemis. Accompanied by Hazel and Frank, he finds the gods weakened by the conflict between Greeks and Romans. Apollo, burdened by guilt and unable to intervene, reveals that the Oracle of Delphi has been taken by Python, preventing any prophecy. Artemis, though also weakened, informs them of the threat posed by Octavian and his army. Leo proposes a deal: he will give Apollo a musical invention in exchange for the final ingredient for the physician’s cure.

Back on the Argo II, he shares his secret plan with Hazel and Frank, who, though horrified, agree to help him.

Jason, Piper, and Leo descend into the ancient temple and find a statue of Hygieia, daughter of Asclepius, who denies them entry for failing to meet absurd medical standards. When the goddess attacks them with her mechanical serpent, Leo uses his ingenuity to reprogram it into "idiot mode," causing it to act ridiculously. With Hygieia and her guardian neutralized, they gain access to Asclepius’ chamber. Time is running out, and the key to saving humanity is within reach, but the battle against Gaia and Octavian’s armies is about to begin.

With all the ingredients gathered, Piper releases the makhai, spirits of battle, to complete the potion. Asclepius warns them that the cure can only revive one person and must be administered immediately after death. Back on the Argo II, Leo pretends to hand the potion to Piper but secretly keeps the real one for himself. In the engine room, he programs a plan using his astrolabe to fulfill the prophecy and ensure the war ends. Before falling asleep, he whispers a promise: he will return to Calypso, no matter the cost.

Chapter 37 Summary – The Blood of Olympus – A Conspiracy in the Legion

Reyna, Nico, and Coach Hedge approach Camp Half-Blood, but the Roman onagers threaten to shoot them down. They decide to land on a yacht named Mi Amor, where they are welcomed by Pegasus, who names Reyna “Friend of Horses.” Soon, a Roman boat arrives carrying Michael Kahale and two centurions sent by Octavian. Reyna tries to reason with them, but Michael, though hesitant, insists on arresting her. Dakota and Leila, the other centurions, reveal that they distrust Octavian and want to help. Just as the situation grows tense, Tyson and Ella arrive alongside Hedge, subduing Michael. Reyna and Nico devise a plan to split up: she will deliver the Athena Parthenos, while Nico, Dakota, and Leila sabotage the onagers to delay the Roman attack. Tyson and Ella will take Hedge to the Greek camp. Before departing, Nico promises Reyna that he will not fail her. The final battle is near.

Chapter 38 Summary – The Blood of Olympus – Reyna’s Plan and Nico’s Sabotage

FAQs – Chapter by Chapter Summary – The Blood of Olympus

Why does Jason call on Juno right before falling in battle?

Because Jason realizes his bond with the minor gods, especially Juno, is essential to the mission’s fate. By calling her name just before passing out, he invokes divine help as a last resort. It’s a desperate but strategic act. This moment marks a strong emotional turn in the story, solidifying his role as the bridge between Greek and Roman demigods, and foreshadows the sacrifice that will define his legacy.

What does the chained statue of Ares found by Piper and Annabeth in Sparta symbolize?

The statue represents suppressed fear and restrained power. Bound, it prevents the makhai—spirits of battle—from being released. By destroying it, Piper not only gains their aid in defeating Mimas but also confronts her own inner panic. This scene symbolizes that true courage isn’t the absence of fear, but the decision to face it. It's a critical moment where emotion and strategy merge in a powerful act of liberation.

What does Nico’s encounter with Hades reveal about death’s role in the saga?

It shows that death is not merely a threat but a guiding force. Hades doesn’t act as an enemy, but as a father and mentor, revealing painful truths. When he says that “some deaths are inevitable,” it prepares both Nico and the reader for the coming loss. It reframes death in the story as something heroic, even necessary. It’s a turning point in Nico’s arc and a thematic cornerstone of the saga’s final act.

Why does Leo keep his secret plan from the rest of the group?

Leo plans to sacrifice himself to fulfill the prophecy and save his friends. Even though they obtain the physician’s cure from Asclepius, he secretly keeps the real one and programs a return plan using his astrolabe. His silence isn’t about distrust—it’s love. He doesn’t want his friends to try and stop him. This selfless move marks his growth from the group’s comic relief to a deeply strategic and emotionally mature hero.

How does Reyna’s character shape the conclusion of the series?

Reyna embodies balance between leadership, trauma, and redemption. As the one who carries the Athena Parthenos, she becomes a symbol of unity between the Greek and Roman camps. By confronting her personal ghosts, her story adds emotional and psychological depth to the finale. She’s not just a warrior—she’s the human bridge that holds reconciliation together. Without Reyna, peace—and victory—wouldn’t be possible.
