Quick Take
- Narration: Jasmin Walker carries Violet Sorrengail’s voice with conviction and pace, keeping a 23-hour listen propulsive even through the book’s most exposition-heavy stretches.
- Themes: Secrets and the cost of keeping them, loyalty in wartime, the expanding scope of a fantasy world mid-series
- Mood: Urgent, emotionally dense, and full of jaw-dropping turns
- Verdict: The third Empyrean book is a strong midpoint entry that expands the world significantly, delivers on the series’ emotional promises, and sets up a finale that readers will not be able to wait for.
I was halfway through Onyx Storm when the revelation hit that I should have seen coming but absolutely did not. I was on my treadmill, which is where I listen to the Empyrean series because Rebecca Yarros’s pacing is somehow perfectly calibrated to a run. I stopped walking. I stood there on a moving belt being genuinely surprised by a fantasy audiobook in a way I had not been since the first time I read Abercrombie. That moment of readerly shock is what Yarros has built the entire series toward, and Onyx Storm delivers it.
This is the third book in The Empyrean series, following Fourth Wing and Iron Flame, and should not be started here. The synopsis is explicit about that, and I will honor it: nothing I write will make this a reasonable entry point for the uninitiated.
Our Take on Onyx Storm
What Yarros has accomplished in three books is the construction of a world that feels genuinely consequential at every level. The dragons are not decorative. The war politics are not backdrop. Violet Sorrengail’s physical vulnerability, her body is not built for a rider’s demands, and her particular combination of intelligence, loyalty, and stubbornness form a protagonist who earns both her victories and her losses. In Onyx Storm, Violet must travel beyond the failing Aretian wards to find allies in unfamiliar lands, carrying a secret that could destroy everything she has built. The external journey and the internal weight of what she knows run parallel, and Yarros manages the tension between them with real craft.
Reviewers have described this as what a midpoint book should be, and that framing is right. The world expands. The political stakes clarify and deepen. The emotional relationships that have been developing for two books are tested in ways that feel proportional to their importance. One reader described the jaw-dropping revelations and political aspects as landing multiple times through the read, which matches my experience precisely.
Why Listen to This Audiobook
Jasmin Walker is the reason this series works as audio. At nearly twenty-four hours, the runtime requires a narrator who can modulate between the war council scenes, the intimate scenes between Violet and Xaden, and the action sequences without losing the listener’s trust in the voice. Walker does this. She does not over-perform the romantic material, which is a real risk in romantasy narration, and she does not flatten the action sequences into monotone urgency. The pacing she brings to the journey sections, where the world-building necessarily slows the plot, keeps the listener grounded rather than restless.
The audio format also amplifies something specific about Yarros’s prose style. The short chapters and frequent scene shifts, which can read as choppy on a page, feel like deliberate propulsion in audio. Walker navigates the transitions smoothly.
What to Watch For in This Audiobook
Listeners who found Iron Flame’s middle sections challenging because of the expanded political scaffolding should know that Onyx Storm requires similar patience in its first quarter. The setup for the journey beyond the wards involves considerable world-building exposition that pays off handsomely later but asks for trust in the interim. Additionally, because this is book three of what is planned as a five-book series, the ending does not resolve everything. It is a midpoint conclusion, not a complete one. Readers who prefer closed endings per volume will find this structure frustrating, though the emotional satisfactions within the book are real and earned.
Who Should Listen to Onyx Storm
Anyone who has finished Fourth Wing and Iron Flame should listen to this immediately. The Empyrean series has built a reader community for good reason, and this entry rewards the investment. Readers of romantasy who have been considering starting the series should begin with Fourth Wing rather than here. Those who have bounced off the first book’s tone, which blends military academy drama, dragon bonding, and explicit romance, will not find this third entry a better entry point. But for readers who are already inside Yarros’s world, Onyx Storm is exactly the continuation the series needed.
Frequently Asked Questions
Can Onyx Storm be listened to without reading Fourth Wing and Iron Flame first?
No. The series is designed to be experienced in order, and the synopsis itself notes this. The emotional and narrative payoffs in Onyx Storm depend entirely on the groundwork laid in books one and two.
How does Jasmin Walker handle the shift between the romantic and the war-narrative sections of the book?
Walker is skilled at modulating between registers without making the transitions feel jarring. She restrains the romantic scenes rather than over-performing them, which keeps the overall tone grounded, and brings energy and clarity to the action and political sequences.
Does Onyx Storm have a satisfying ending or does it end on a cliffhanger?
It is a midpoint ending in a five-book series. The core emotional arc of this volume reaches a resolution, and certain revelations are fully paid off, but the overarching conflict is not resolved. Readers who need narrative closure per volume should plan accordingly.
Is the world-building in Onyx Storm as demanding as it was in Iron Flame?
The world expands significantly in this book, particularly in the sections involving the journey beyond the Aretian wards. The first quarter requires patience with new political and geographic information, but the payoff in the later sections is proportional to that investment.
