Onyx Storm by Rebecca Yarros is the third book in The Empyrean series (paid links). I had originally thought it was the final book, but it now looks like she is planning for five volumes in this series.
You can find my reviews of the earlier books below:
Here is the blurb:
After nearly eighteen months at Basgiath War College, Violet Sorrengail knows there’s no more time for lessons. No more time for uncertainty. Because the battle has truly begun, and with enemies closing in from outside their walls and within their ranks, it’s impossible to know who to trust.
Now Violet must journey beyond the failing Aretian wards to seek allies from unfamiliar lands to stand with Navarre. The trip will test every bit of her wit, luck, and strength, but she will do anything to save what she loves—her dragons, her family, her home, and him.
Even if it means keeping a secret so big, it could destroy everything. They need an army. They need power. They need magic. And they need the one thing only Violet can find—the truth. But a storm is coming…and not everyone can survive its wrath.
I think it going to be impossible to write this review without some spoilers from the previous two books, so be warned going into this. I will try to avoid spoilers for this book though.
I enjoyed Onyx Storm more than Iron Flame, but not as much as Fourth Wing. I think that was partly because the first book was more focused and everything in Basgiath was new to me as a reader, so the experience of reading the story mirrored that of Violet experiencing the school. Onyx Storm has a massive sprawling plot, with a growing host of characters, more expansive politics, and takes place over an enlarging geographic region. While I often love that kind of thing, it made me feel like I didn’t know which direction things were heading.
Onyx Storm is filled with shocking events. I found myself wondering what else could possibly happen at several points in the book, only to be surprised by another twist a few pages later. For the most part, these surprises worked and didn’t feel forced, although the way the story has developed makes me want to re-read the series before the next book is released so that I’m not missing some of the smaller details.
Violet and Xaden’s relationship is challenged after he turns venin at the end of Iron Flame. He struggles against this destructive power and tries to keep his change secret from everyone but Vi and their dragons. It has to be tough as an author to keep the romance fresh through multiple books. Something has to keep the couple apart, whether it’s a fight, a breakup, political pressure, or becoming a power-sucking red-eyed demon, in order for them to have a reason to make up and keep things hot. I think that the author does a decent job of this through this book, but nothing that is much different than what happens in the first two books.
I pre-ordered this novel and the Deluxe Limited Edition is a gorgeous book. I love the design and the color choices with the black fading into silver. This edition also features sprayed edges with what else – dragons!
