Ether-laced blood never lies, and in Half-Blood, every scar tells a story that can’t be erased with magic. In this first installment of Jennifer L. Armentrout’s Covenant series, Alexandria’s fate doesn’t begin with a choice—it begins with an escape: a ruined warehouse, a titanium shovel, and a memory more painful than any daimon bite. From that moment on, she carries more than just her mixed blood; she carries questions that echo through every corridor of the Covenant and prophecies that whisper from the past.
Across twenty-one chapters of ruthless training, buried truths, and forbidden longing, Half-Blood introduces a world ruled by order: pure-bloods dominate, half-bloods obey, and daimons hunt without mercy. But Álex was never meant to kneel. Not even when the truth about her mother threatens to shatter her from within. With a gripping blend of mythology, danger, and slow-burning desire, this book lays the foundation of a saga where every choice comes with a price—and sometimes, that price is your soul.
Because no one here is just what they seem, and the rules meant to protect may be the ones that destroy you. To truly understand how this universe begins, don’t miss this essential guide: Reading order of the Covenant series ➤
Chapter-by-Chapter Summary
Chapter 1 Summary – Half‑Blood – Mixed‑Blood: Flight Among Daimons and Sentinels
Álex hides in an abandoned Georgia factory while several daimons track her, reminding her of her mother’s violent death in Miami. Armed with a titanium shovel, the only metal capable of killing them, she flees down the halls until confronting and destroying one. Cornered by more daimons, she tries to escape, but a wall of fire stops her. Then Aiden St. Delphi appears, a pure‑blood sentinel she met years earlier at the Covenant. Alongside other sentinels, he eliminates the daimons, although one manages to bite Álex and drain her aether, leaving her marked and in pain. Aiden assists her and forces her to withdraw when she, consumed by rage and trauma, tries to attack him upon recalling her abandonment of the Covenant and her mother’s death. Finally, Aiden uses compulsion to stop her, and Álex loses consciousness while the sentinels carry her out of the place bound for the Covenant.
Chapter 2 Summary – Half‑Blood – Forced Return to the Covenant
Álex awakens in a Covenant vehicle leaning on Aiden and discovers he brought her there using compulsion, something ethically questionable with mixed‑bloods. During the journey to Deity Island, she recalls the structure of her world: pure‑bloods control the elements, mixed‑bloods serve or train, and daimons are addicted to aether. Upon arrival, the Covenant provokes nostalgia and pain over her mother. Aiden explains that her uncle Marcus is now the dean. After washing up and receiving training clothes, Álex examines the daimon mark on her neck and reflects on the cruelty of the system and the fate of mixed‑bloods. Aiden returns for her and brings her before Marcus. In his office, Marcus blames her mother Rachelle for fleeing the Covenant and considers Álex problematic due to her history of indiscipline. Despite her talent, he decides to deny her training and proposes sending her as a servant to her stepfather Lucian’s house.
Chapter 3 Summary – Half‑Blood – A Conditional Opportunity
Marcus’s decision leaves Álex devastated, but Leon and Aiden intervene, highlighting that she killed daimons alone and possesses exceptional potential. Marcus insists that her temperament makes her dangerous to the Covenant and that he cannot afford to watch her. Aiden offers to train her personally over the summer, assuming full responsibility for her conduct. After a tense negotiation, Marcus agrees on the condition that she will be expelled if she fails. Later, Álex meets with old mixed‑blood friends like Caleb and Jackson, who are surprised by her return and her experience fighting daimons. The conversation turns hostile when Lea Samos provokes her by insinuating that her mother fled after hearing a prophecy from the oracle Piperi related to Álex. Unable to contain herself, Álex attacks Lea, confirming the troublesome reputation Marcus reproaches her with, while also reaffirming her determination never to submit to servitude.

Chapter 4 Summary – Half‑Blood – Guilt, Control, and Training
After the altercation with Lea, Caleb prevents Álex from worsening the situation and convinces her to withdraw. The revelation about the oracle’s prophecy obsesses her, making her question the real reasons her mother fled the Covenant. Caleb suggests that Piperi might still be alive and could perhaps give her answers. Later, Aiden surprises her by returning confiscated clothes and confronts her about the fight, reminding her that any mistake will fall on him. In her room, Aiden demands self‑control and explains that rumors cannot dictate her actions if she wants to return to the Covenant and avenge the daimons. Álex confesses her guilt for not asking for help in time to save her mother. Aiden tries to ease that burden, assuring her it was not her responsibility, though Álex cannot fully believe it. She decides to accept the training, knowing her future depends on mastering her rage and surviving the summer.
Chapter 5 Summary – Half‑Blood – Basic Training and Strict Rules
Álex begins training with Aiden in the Covenant gym, feeling like she’s going back in time, though she perceives clear differences between him and past instructors. Aiden imposes warm‑up exercises, order, and discipline, making it clear she hasn’t earned the right to use titanium weapons. He evaluates her level and concludes she remembers little of her previous training. He announces eight‑hour days and forces her to strengthen her body with gym work and proper nutrition, handing her a protein shake. Aiden establishes strict rules about outings, consumption, and supervision, insisting it’s all for safety. The training focuses on falls and recovery, where Álex shows initial clumsiness and pride, falling repeatedly until regaining correct technique. After a mandatory birth control injection, she returns to training exhausted and sore. Aiden encourages her, talks about scars as medals, and advises stretching. Later, Caleb visits with clothes and gossip, and Álex reflects on the Covenant, hierarchies between mixed and pure, and the injustice of the system, trying to convince herself that being there is better than any alternative.
Chapter 6 Summary – Half‑Blood – Disobedience and a Brutal Lesson
During intense blocking training, Álex fights through pain and fatigue while Aiden corrects each movement and demands absolute attention. Although she manages some blocks, it’s clear she’s far behind and her reflexes are still insufficient. Marcus appears to observe and provokes her, agreeing to fight her as a test. Ignoring Aiden’s warnings, Álex faces him confidently, blocks several strikes and grows cocky, until Marcus surprises her with a brutal hold that leaves her immobilized. The experience shows her that against a real enemy, she would have died. Marcus leaves, making it clear that Álex’s attitude is her biggest problem. Aiden harshly reprimands her, insisting that obedience is essential to be a Sentinel. Álex feels humiliated, questions Marcus’s hatred toward her, and acknowledges that she lost years of training. Later, Caleb invites her to a party to distract her. Though exhausted and frustrated, Álex agrees to go out, convinced she needs to forget the day’s failure, even knowing she risks getting into more trouble within the Covenant.
Chapter 7 Summary – Half‑Blood – Party, Tensions, and a Warning in the Dark
At Zarak’s party, Álex reunites with old friends and meets Deacon St. Delphi, Aiden’s brother, whose carefree and provocative attitude contrasts with his brother’s seriousness. Amid drinks and music, tensions arise with Lea and comments about the rigid separation between pure and mixed‑bloods. Álex hears rumors about a possible petition to change the Order of races, which ignites her outrage at the injustice of the system. She flirts with Jackson without any real intention of going further and decides to leave alone, rejecting following the group off the island. On the way back to the Covenant, she feels an unsettling presence near the swamp, but Aiden appears and stops her, reminding her of the danger of being alone. He admits they watch the young ones and scolds her for drinking and breaking rules, though he promises not to report her. They walk together talking about responsibilities, losses, and the weight of being a Sentinel. Aiden acknowledges remembering Álex from the past and she discovers his more human side, closing the night with an unexpected connection between them.
Chapter 8 Summary – Half‑Blood – The Oracle Piperi’s Warning
Álex endures a punishment of intensive training imposed by Aiden, spending hours in the gym among weights and cardio, where the tension between them softens with ironies and unexpected complicity. Later, alone in her room, she reads an old book of myths and discovers unsettling information about the Apollyon, unique mixed‑bloods capable of controlling all elements, including the tragedy of Solaris, executed alongside another Apollyon by divine order. Days later, during a beach party, Álex observes political tensions between pure and mixed‑bloods and avoids Jackson, while Caleb reveals repressed feelings for Olivia. On the way back to the residence, they encounter Grandmother Piperi, the oracle. The elderly woman claims to have spoken with Álex’s mother and utters cryptic warnings about love, necessity, and destiny. Finally, Piperi takes Álex by the shoulder and prophesies that she will kill those she loves, leaving Álex terrified and filled with doubts about her future and the true reason her mother fled the Covenant.
Chapter 9 Summary – Half‑Blood – Distraction, Guilt, and Dangerous Closeness
During a training session with Kain, Álex performs poorly, distracted by Piperi’s prophecy, and takes a blow that leaves her sore and humiliated. Aiden abruptly stops the fight and takes her to the medical room, where he discovers that Álex’s back is covered in severe bruises she had ignored. As he treats her with an ointment, their conversation turns to the guilt they both carry over their parents’ deaths and how that guilt shapes their choices. Aiden insists that oracles speak only of possibilities and that Álex is not responsible for the past, encouraging her not to be ruled by fear. The physical closeness and Aiden’s care create intense emotional tension between them, interrupted by Leon’s arrival. Before leaving, Aiden promises to continue the conversation later, leaving Álex confused by her feelings, aware of the barrier between pure‑blood and mixed‑blood, and still deeply shaken by the oracle’s words.
Chapter 10 Summary – Half‑Blood – The Apollyon and an Impossible Truth
Aiden informs Álex of Lucian’s imminent visit, her legal guardian, and warns her that her stay at the Covenant is in danger. Before the meeting, Álex receives a green student uniform, a gesture from Aiden that strengthens her sense of belonging. In the great hall, the arrival of Lucian and the Apollyon causes a stir. Álex senses a surge of aether and notices strange marks on the Apollyon that no one else seems to see. Later, Aiden confirms that the Apollyon’s name is Seth, though he avoids further explanation. In Marcus’s office, Lucian surprises Álex with a warm attitude and offers that she live with him, giving up training as a Sentinel. Marcus supports the proposal, citing a conflict of interest. Álex refuses, determined to become a Sentinel, but the meeting takes a devastating turn when Marcus reveals a truth that changes everything: her mother is not dead.
Chapter 11 Summary – Half‑Blood – The Truth About Her Mother
Marcus confirms that Álex’s mother is still alive and was turned into a daimon after the attack, destroying any hope of mistake or confusion. The revelation awakens crushing guilt as Álex realizes she may have abandoned her mother while she was still breathing. Marcus explains that another daimon drained her and that she was seen in Georgia shortly afterward, opening the possibility that she retains memories and may be searching for Álex. The idea is unbearable, yet Álex refuses to give up and declares she will fulfill her duty as a mixed‑blood without letting it affect her training. Marcus agrees to let her remain at the Covenant under strict conditions. As she leaves, Álex confronts Aiden for hiding the truth, feeling betrayed and rejected, and walks away unable to hear his explanations. Alone, the impact completely breaks her: she vomits, remembers her mother’s cold body, and accepts a devastating truth. If they meet again, neither will survive, and that certainty marks an irreversible turning point.
Chapter 12 Summary – Half‑Blood – Rage, Desire, and Warnings
Álex emerges from her Sunday confinement and, overwhelmed by guilt, unleashes her turmoil in the training room, striking dummies until pain turns into precision and strength. Aiden appears and agrees to face her, allowing her to release her pent‑up rage. The fight exposes reproaches over the hidden truth and a shared wound neither can put into words. Physical tension turns into an impulsive kiss that both abruptly stop, leaving shame, confusion, and a dangerous distance behind. Álex flees and encounters Seth, who insists on knowing why she matters to the Council and senses something different about her, even in the daimon mark. Seth suggests her arrival was no coincidence and warns that if she does not consider her mother dead, a reunion will be fatal. Álex returns unsettled, aware that she draws dangerous forces and that her identity raises questions no one is ready to answer.
Chapter 13 Summary – Half‑Blood – Lake Lure and the Final Decision
Training continues under silent tension, with Álex performing better while Aiden keeps his distance and expresses caution regarding Seth and Lucian. Kain joins some sessions, and Seth appears frequently on campus, causing unease. The semblance of normality shatters with news of a daimon attack in Lake Lure: pure‑blood families murdered, mixed‑blood servants drained, and two guards missing, including Kain. The scale of the massacre shakes the Covenant and wipes away any distraction. Aiden returns exhausted from the investigation and reveals the unthinkable after reviewing the footage: Álex’s mother was one of the daimons involved and is dangerously close. The comfort they find in each other is both necessary and forbidden within the hierarchies. Álex accepts a responsibility that tears her apart inside: if her mother has killed, she must stop her. Duty, love, and horror merge into a decision that defines her path with no possibility of turning back.
Chapter 14 Summary – Half‑Blood – The Apollyon’s Storm
During training, Álex pretends to be fine and vents her frustration by pounding dummies, while Aiden senses that something inside her has broken. Seth’s silent appearance sparks immediate tension, intensified when he coldly mentions the Lake Lure attack and Álex’s mother. Alone together, Seth confesses he is there because of her and reveals that he can summon storms when agitated. Álex realizes she can see the Apollyon’s shifting marks, something no one else perceives, and the energy between them becomes intense and dangerous, awakening an involuntary attraction she manages to break before touching him. Later, she talks with Caleb about the oracle’s prophecy and the possibility of having to kill her mother. Over the following week, rumors spread, hostility grows, and Álex becomes the focus of stares and whispers. Aiden supports her, strengthens her training, and reminds her of her purpose, while Álex struggles between hope, guilt, and the certainty that her duty may force her to face the unthinkable.
Chapter 15 Summary – Half‑Blood – The Awakening of a Forbidden Truth
After a violent confrontation with Cody at a social gathering, Álex loses emotional control and is restrained by Seth’s intervention, whose presence imposes silence and fear. Later, Seth confronts her and grabs her arm, unleashing an explosion of energy that connects them through a blue cord, sharing thoughts and emotions. Convinced they have been manipulated, Seth drags Álex to Lucian’s house and bursts in violently. There, Lucian reveals the truth: the oracle predicted that Álex would become the second Apollyon upon turning eighteen, and Seth was brought to the Covenant to confirm it. Together they would be two halves destined for limitless power after the Awakening. Álex rejects the idea of belonging to Seth and flees in terror. Seeking answers, she goes to Aiden’s cabin, where he takes her in without judgment. Through confessions, Álex understands that her mother fled to protect her from a tragic fate, and though fear consumes her, Aiden offers support and safety amid the chaos threatening to destroy her world.
Chapter 16 Summary – Half‑Blood – Kisses, Secrets, and Betrayal
In Aiden’s cabin, Álex finds comfort as she tells him everything that happened with Seth and Lucian, including the revelation that she is the second Apollyon.

Emotional closeness turns into intense, forbidden intimacy, culminating in desire‑laden kisses that nearly cross an irreversible line. Leon’s arrival interrupts the moment with news that Kain has been found alive. After returning to her residence, Álex cannot calm her anxiety and secretly goes to the infirmary. There she discovers a brutal scene: several nurses murdered. Kain confesses that he lied to the Sentinels and reveals his transformation, admitting he killed to feed. Horror becomes reality when he attacks Álex with superhuman strength. In that instant, she understands the impossible truth: Kain is no longer a mixed‑blood, he has become a daimon, and her world shatters once again beyond repair.
Chapter 17 Summary – Half‑Blood – The Immune Daimon and the Price of Akasha
Álex confronts Kain in the infirmary and discovers that her former companion is now a mixed‑blood daimon capable of completely concealing himself. Kain mocks her, explains the process of slow draining, and reveals that Álex’s mother was the one who turned him and continues killing while searching for her. The escape attempt fails, and Álex is forced to fight without weapons until Aiden bursts in and battles Kain. The titanium dagger doesn’t kill him, revealing a terrifying truth: mixed‑blood daimons are immune to titanium. The fight escalates when reinforcements and Seth arrive, and Aiden uses akasha to destroy Kain for good. After the battle, Álex is in shock, aware that the world has changed irreversibly. Marcus demands explanations, and Álex recounts what happened, while Aiden confirms that Kain spoke of her mother. Pain, guilt, and fear intertwine, and Álex realizes the threat is far greater than anyone imagined.
Chapter 18 Summary – Half‑Blood – The Escape and the Impossible Reunion
Determined to stop her mother, Álex leaves the Covenant disguised as a Sentinel and ventures into the mortal world convinced she can handle it. Caleb follows and tries to stop her, but their encounter is interrupted when Rachelle, now a daimon, appears. Her human appearance and maternal voice paralyze Álex, who is unable to shoot. Rachelle exploits that weakness to capture her and take her, along with Caleb, to a cabin in Gatlinburg. Upon waking, Álex discovers that Caleb is being held and marked by other daimons. She tries to protect him but is easily overpowered. Rachelle reveals her plan: to keep Álex away from the Apollyon and turn her into a daimon to save her from a worse fate. The threat is clear and cruel, and Álex finds herself torn between love for her mother and terror at what she intends to do, with no way to escape.
Chapter 19 Summary – Half‑Blood – Broken Promises and Spilled Blood
Álex is repeatedly drained by the daimons under her mother’s supervision, while Caleb is kept as leverage to ensure her obedience. The physical pain and loss of aether gradually break her, leaving her exhausted and desperate. Rachelle promises that Caleb will live if Álex doesn’t flee or resist, and Álex agrees, even knowing that promise dooms her. Hours pass in a haze of bites, threats, and delirium, while Rachelle speaks of a future war and daimon domination. When Daniel goes too far and brutally attacks Álex, Rachelle intervenes in fury, creating an opening. Álex seizes the chaos, frees Caleb, and they flee into the rain. Rachelle chases them, unleashing fire to stop them, and Álex realizes she can no longer see her as a mother. On the brink of collapse, she is rescued by Aiden, convinced that nothing will ever be the same and that the war has already begun.

She learns that Caleb is safe and that the Council is investigating what happened with Kain, confirming that the world has changed. A necessary conversation arises between her and Aiden about what happened between them, filled with attraction, concern, and painful boundaries. Aiden makes it clear that while his feelings are real, he cannot risk Álex’s future or condemn her by breaking the Breed Order.

Against her fears, Marcus allows her to stay at the Covenant and continue her training, noting that her progress has been exceptional despite lacking formal instruction. He announces that Aiden will continue training her and that she will also have sessions with Seth, a decision Álex accepts with relief. Later, Seth visits and candidly explains the nature of their Apollyon bond, revealing he can feel her pain, locate her, and that after the Awakening, their union will be dangerous and unbalanced, though there may be a way to separate to avoid losing control. Álex processes the information uneasily but reaffirms her determination to keep living and training. Finally, she holds an intimate ceremony with Caleb to honor her mother and the fallen, finding peace in saying goodbye, while Aiden watches silently, proud, accepting that Álex has chosen to move forward.

FAQs – Chapter by Chapter Summary – Half-Blood
What does Piperi’s prophecy mean for Alex’s future in Half-Blood?
It predicts that she’ll kill those she loves, planting a seed of fear that shapes her every move. More than just words, this prophecy becomes the emotional backbone of her arc—fueling doubt, guilt, and the desperate hope to rewrite fate. The prophecy sets up a devastating dilemma: is destiny inevitable, or can Alex break the cycle before it breaks her?
How does discovering she’s the second Apollyon change Alex’s role in the Covenant?
It catapults her from a rebellious mixed-blood into a symbol of dangerous potential. Being the second Apollyon makes her a threat, a target, and a pawn in larger power games. From that point on, her existence challenges the system’s very foundation—and forces her to question whether she’s fighting for survival or something even bigger: freedom.
Why is Kain’s transformation into a daimon such a game-changer?
Because it reveals that even the people Alex trusts can become monsters. Kain’s mutation into a daimon immune to titanium shows that the rules have changed—and the threat is now internal. It breaks any illusion of safety within the Covenant, turning allies into possible enemies and forcing Alex to question everything she thought she knew.
What makes Aiden’s relationship with Alex so emotionally significant?
He isn’t just a love interest—he’s her compass in chaos. Bound by Breed Order laws, Aiden walks a tightrope between duty and desire, offering Alex empathy without overstepping. Their connection brings a raw honesty that grounds her when the world spins out of control, adding weight and warmth to a narrative steeped in fear and uncertainty.
How does Alex’s mother shape the novel’s core conflict?
Her transformation into a daimon—and continued pursuit of Alex—turns the story personal. The person Alex once loved most becomes a symbol of everything she fears: losing control, losing self, losing the ones she cares for. Their relationship evolves into a chilling mirror, forcing Alex to face the possibility that love can both save and destroy.
