Onyx Storm Audiobook Review

What it's about

Nearly eighteen months into Basgiath War College, Violet Sorrengail is done with lessons - the war she's been training for has actually started, and it's coming from two directions at once: enemies outside Navarre's walls, and people inside her own ranks she can no longer be sure of. That forces her hand: she has to leave the failing protection of the Aretian wards behind and go looking for allies in unfamiliar territory, betting her dragons, her family, her home, and the man she loves on the trip paying off. She's also sitting on a secret large enough to undo all of it if it gets out. What she's actually hunting for isn't more firepower - the book is explicit that an army and magic alone won't be enough - it's the truth only she's positioned to find. Onyx Storm is the third book of the Empyrean series, following Fourth Wing and Iron Flame, and the publisher is direct about it being a continuation rather than an entry point: read (or listen to) the first two before this one.

Why the audiobook

The cast has grown rather than turned over: Teddy Hamilton and Rebecca Soler, who narrated both Fourth Wing and Iron Flame, are joined here by Jasmin Walker and Justis Bolding for a four-narrator lineup, up from two. For a returning listener, that's a real continuity signal - the two voices you already associate with Violet and her world are still there, with more cast added as the story's scope widens rather than replaced outright.

Who it's for

This is for readers already invested in Violet's story after the first two Empyrean books - the stakes here assume you know who she's protecting and what she's already lost to get here. It's not a jumping-on point, and the publisher isn't shy about saying so. If you haven't read Fourth Wing or Iron Flame yet, start there; arriving at Onyx Storm cold will cost you most of what makes the stakes land.

The verdict

With 39,674 Audible ratings at last check, Onyx Storm sits among the more heavily-rated audiobooks we've covered - consistent with a series that's kept its core narrators through three installments while raising the stakes each time. If you're caught up on the Empyrean series, this is very much worth the next credit; if you're not, that's genuinely a feature of how the series is built, not a knock on this specific entry.
