Review

On its surface, Onyx Storm is a dragon-rider quest to find a lost breed of dragon and cure a poisoned soul. Its dedication—"Get your leathers. We have dragons to ride."—promises the adrenalized, inclusive adventure that made the Empyrean series a phenomenon. But the book that follows is far less interested in the triumphant return of a hero than in the grinding, piece-by-piece loss of one. Rebecca Yarros has, with this third volume, done something quietly devastating: she has placed a love story at the center of an epic fantasy and then, page by page, made the object of that love unsalvageable. The quest for a cure does not fail because the protagonists are not clever enough, or because the map runs out; it fails because the universe, in the form of the long-lost irid dragons, delivers an answer that no amount of grit can overturn. "The power exchange kills the soul one piece at a time, and death has no cure." What remains is not a story about fixing the beloved, but about loving across an impossible boundary, about choosing fidelity while the ground dissolves under your feet. That is the book’s most distinctive and emotionally honest achievement.

Violet Sorrengail opens the story with a vow that reads like a mission statement: "I will not die today. I will save him." Her addendum to the Book of Brennan, the in-world catechism that frames every cadet’s moral world, is a declaration of romantic agency. She has watched Xaden Riorson channel from the earth to save her life, turning himself into a venin—a dark wielder whose soul is consumed incrementally—and she refuses to accept that as the end. The novel’s first movement, set in the halls and battle-scarred courtyards of Basgiath War College, shows the immediate aftermath of that sacrifice: Xaden can now sense other venin, his eyes flicker with amber and red, and he pushes Violet away with the classic protest "I could reach the rank of Maven, lead armies of dark wielders against everyone we care for… and I would still love you. What I did doesn't change that. I'm not sure anything can." It is a confession of terrifying constancy, not comfort, and the book lets the terror sit.

The architecture of Onyx Storm is built precisely to dismantle the hope Violet clings to. The first eight chapters compress multiple political crises—a venin infiltration disguised as scribes, the squad’s treasonous alteration of the wardstone to allow gryphon fliers to wield within Navarre’s borders, Violet’s arrest for high treason and subsequent pardon—into a breathless sequence that demonstrates the war’s encroachment on every institution. Yet the real engine of the narrative is the departure from the known world. Violet, having cracked her dead father’s locked manuscript with the password AIMSIR, leads a handpicked squad across the Arctile Ocean to the southern isles in search of Andarna’s kind, the irids. The crossing itself is a kind of severance: all dragons lose communication except Violet, whose dual bond makes her a living bridge. The image of the squad flying in near-silence, their psychic links cut, already hints that the old certainties will not survive this quest.

The isle chapters have been criticized as episodic, and it’s true that Deverelli, Unnbriel, Hedotis, and Zehyllna function partly as a series of set-pieces. But each isle also strips away a layer of the squad’s—and the reader’s—illusions about power, history, and belonging. In Deverelli, a merchant city where gems speak louder than blood, Violet retrieves her father’s passcode-locked tomes from the bookseller Narelle, only to watch Prince Halden’s arrogance provoke a dinner-table massacre; Xaden channels to kill a dozen guards, and Violet must negotiate with a panther-keeping king by leveraging the eggshell of the rarest dragon in existence. The Amelian Citrine, bought from Viscount Tecarus with promises and bargains, becomes the price of an audience, but the real currency is always leverage, always the body of someone you love. On Unnbriel, Violet, Xaden, and Dain win a three-way trial by combat against the queen herself, but the political cost is a demand for twelve dragon eggs—two of each breed—a transaction that recalls the original Krovlan uprising’s aim of trafficking dragons. The book does not let its heroes forget that the southern isles have their own histories of colonial extraction and that the Empyrean’s dragons are, to some, cargo.

The Hedotis chapters deliver the emotional pivot that clarifies what the book is really about. There, Violet discovers Xaden’s mother Talia married to a triumvir, living the life she chose after abandoning her son. The reunion is brutal. Talia wants reconnection; Xaden can offer only fury. A confiscated letter from Fen Riorson appears earlier as an epigraph, declaring that "the most useless word in the language of aristocracy has always been and will forever be: love. Marriage is a necessary evil to secure the line. Nothing more. Save love for your children." The book’s argument is exactly the reverse: parental abandonment is the wound that does not close, and the love Xaden and Violet share is not ornamental but existential. On Hedotis, the squad survives a poisoning attempt—arisinmint-tarsilla in a chocolate cake—and Violet retaliates by poisoning the hosts to force an antidote, a maneuver that makes Garrick’s survival possible but also demonstrates the ruthlessness this quest now requires. That ruthlessness is made explicit on Zehyllna, where the "gift" game gives Trager an arrow through the heart. His gryphon Silaraine collapses and dies of the broken bond, and Violet, forced to thank the archer who murdered her friend, marks the moment internally: "Thank you. Fuck them. Another piece of my humanity." The sentence is a small masterpiece of compressed grief and self-awareness. The mission is devouring her, piece by piece, in a smaller mirror of what is happening to Xaden.

Then the irids arrive. Six of them find the squad on a black-sand isle, and the confrontation with Andarna is the novel’s theological core. The dragons reject her as a "weapon," a creature shaped by human violence, and in the same breath deliver the verdict that shatters the quest’s premise. When Andarna argues that if dark wielders trade their soul, they can surely reclaim it, the female irid corrects her: "It is not a trade. The soul is not kept by the earth as dark wielders steal its magic. The power exchange kills the soul one piece at a time, and death has no cure." The language is absolute. There is no hidden loophole, no seventh breed secret that will reverse the process. The cure does not exist. The book has spent five hundred pages building toward an answer that is a door slammed shut. Andarna, rejected by the family she hoped would accept her, is eventually taken by Leothan to be raised among the irids, and Violet releases her with the words "I love you and I want you to feel complete. I want you happy and safe and thriving. I want you to live. Even if it’s not with me." It is a leave-taking that parallels the larger arc: love, here, is the willingness to let go when holding on becomes a form of harm.

What follows in the back third of the novel is a demonstration of what it means to keep fighting when the metaphysical answer is no. Violet discovers she is a dream-walker, an inntinnsic ability inherited from Andarna that lets her enter sleeping minds, and this second signet becomes both a new form of intimacy with Xaden and a tactical asset. The squad defends Aretia against a wyvern horde, and Leothan fires the wardstone to save the province, but the cost is Andarna’s departure, which plunges Violet into three days of catatonia—a stretch of grief rendered with unglamorous physicality: she refuses food, she cannot leave bed, she is hollowed out. The book refuses to cut away from this. Only Mira’s blunt affection pulls her back, and even then the return is fragile. It is one of the novel’s quiet strengths that it lets breakdown be breakdown, not just a plot beat before the next action sequence.

The climactic battle at Draithus is, structurally, the most ambitious section of the book. Yarros splits the narrative into multiple points of view: Violet facing Theophanie, her silver-haired Maven antagonist and former high priestess of Dunne; Rhiannon commanding the Medaro Pass with half the squad against seventeen wyvern; Imogen racing through a turret to save Quinn; Xaden fighting alone to rescue Sgaeyl. The multi-POV shift is a functional necessity—the conflict has spread beyond one character’s perception—but it also accomplishes something thematic. It drives home the lesson that Tairn delivers when Violet is paralyzed by the three-front problem: "You are the weapon and will have to learn to accept the sacrifice of others in your name if you want to win this war." Leadership in this world is not the orchestration of victory; it is the acceptance of loss. Quinn dies in Imogen’s arms with the line "We made it a good one." Trager is gone. Andarna is gone. The list of sacrifices is not theoretical. Violet kills Theophanie with a temple-blessed marble dagger that Aaric, the hidden precog, has slipped into her possession, and the moment is framed as act of divine wrath—"Dunne is a wrathful goddess to high priestesses who turn their backs on Her"—but it costs her everything. Because while she is winning that duel, Xaden, seeing Sgaeyl netted and wounded, channels from the earth one final time and turns fully venin, killing riders and dragons, before vanishing.

The novel’s ending is a one-two punch that refuses catharsis. Violet wakes twelve hours later in Aretia’s courtyard wearing the emerald ring of the Blade of Aretia, the sword whose missing stone is now on her finger. She has been married by proxy blessing, and Xaden is gone, leaving only a two-line note: "Don’t look for me. It’s yours now. He’s gone." The grammatical shift in that note—"He’s gone," not "I’m gone"—is the novel’s final, chilling admission that the person Violet loved may no longer be the person who exists. The irids were right. The soul dies piece by piece. And yet the ring is there. The marriage happened. The love was real. Yarros refuses to let the tragedy negate the relationship that preceded it.

This refusal is where the book’s genre identity snaps into focus. Onyx Storm sits squarely in the emerging romantasy tradition—a hybrid that takes the emotional architecture of romance fiction and grafts it onto the worldbuilding scale of epic fantasy. The canonical traditions of "fantasy" and "romance" are both present but neither dominates; the book is a third thing, as the library’s classification map acknowledges with the unmapped marker "romantasy." Within that hybrid space, the book engages seriously with a catalogue of canonical topics: love, sexuality, grief, trauma, death, family, war, disability, mental health, ethics, political freedom, and colonial subjugation. But it also introduces elements the library’s controlled vocabulary cannot yet capture: venin-soul-corruption as a metaphor for losing someone to addiction or illness, the distinction between first-love and chosen-love, and the experience of being judged unfairly by the very community whose acceptance you crave. These unmapped concerns are the emotional engine of the story, and they mark the book as a contribution to the developmental novel as much as the adventure novel.

The in-world documents that serve as chapter epigraphs—letters from Fen Riorson, Lilith Sorrengail’s unsent correspondence, Major Afendra’s unauthorized guide to the Riders Quadrant, Colonel Kaori’s field guide to dragonkind, recovered journals of General Melgren, the draft history of the Second Krovlan Uprising by Asher Sorrengail—are not mere set dressing. They constitute a paper trail of contested history, suppressed memory, and institutional control. The book is, in quiet moments, a critique of how history is written and who gets to write it. Jesinia Neilwart, the scribe stripped of her adept path, becomes the official researcher for the quest squad, embodying the idea that the production of knowledge is always political, always subject to the whims of the powerful. This attention to suppressed narrative aligns the book with larger fantasy traditions that interrogate empire and propaganda, even if the primary story remains intensely personal.

All of this comes with the baggage of its form. Onyx Storm is a third volume in a planned serial; it does not end so much as pause, and readers who crave resolution will find only a razor’s edge. The isle quest, while thematically purposeful, can feel like a travelogue stretched over too many stops, and the sheer mass of the cast—Lynx manifesting a shadow signet to "balance" Xaden, Aura Beinhaven’s brief antagonism, Captain Grady’s controversial squad choices—occasionally crowds out the emotional intimacy that is the book’s true strength. The explicit sexual content, which the author’s own content note warns is "shown on the page," will be too much for some readers while being precisely what others want from the romantasy genre. The violence is equally unflinching: a serving of a severed head to panthers, a throat slit, a character burned alive by an ally’s signet, a squadmate’s slow death in a friend’s arms. This is not a book for the squeamish, nor is it a book for younger adolescents despite its YA-adjacent thematic concerns.

But what the book gets right, it gets right with startling emotional precision. The developmental scaffolding—questions about how to love someone who is changing in frightening ways, how to keep functioning through overwhelming grief, where the line falls between loyalty and self-protection—is not laid on top of the story like a lesson plan; it emerges organically from characters making terrible choices and living with the consequences. Violet’s arc is not about becoming powerful but about accepting powerlessness. Xaden’s arc is about the dignity of fighting a losing battle against yourself. Sawyer, after losing his leg, does not receive a magical fix; he designs his own adaptation, with his dragon’s help, on his own timeline, and the book treats this not as a side plot but as a quiet insistence that changed bodies are not diminished ones. The squad’s insistence that "bad things happen when we aren’t together" is tested repeatedly, and the book never pretends that togetherness is enough to save everyone. Imogen’s grief over Quinn is not resolved; it sits inside her, raw and immediate, the way grief does.

The book’s great French horn line, the sound that echoes after the last page, is the irids’ verdict. There is no cure. And yet Violet puts on the emerald ring. The love story does not end with a kiss; it ends with a command: "Don’t look for me." That is the position Onyx Storm takes, and it is a braver position than the genre usually allows. In a literary landscape where romantic fantasy often trades in guaranteed happy endings—where the fated mates always find their way back—Yarros has written a love story about the possibility that they won’t, and asked her readers to sit in that possibility without flinching. The book is not flawless; it is too long, too busy, and too comfortable leaning on cliffhangers as a substitute for closure. But its core honesty is rare. It tells the teenagers and young adults who are its true audience something they do not often hear from the stories marketed to them: that sometimes you cannot fix the person you love, that grief can flatten you for days, that leadership is not a reward but a weight, and that the right thing to do is still the right thing to do even when it costs you a piece of your soul. That is a message worth delivering, and Onyx Storm delivers it with a dragon’s roar.
