Onyx Storm is the third book in Rebecca Yarros’s Empyrean series, which is planned to include five books.[4] The first book, Fourth Wing, chronicles the protagonist Violet’s first year at the fictional Basgiath War College, where she becomes a dragon rider. The second book, Iron Flame, follows Violet and her friends and allies as they work to fight evil magic-wielders.
Although Iron Flame (November 2023) came out only about six months after Fourth Wing (May 2023), Yarros said that she would not write Onyx Storm as quickly.[5] It was ultimately scheduled for release on January 21, 2025, more than a year after Iron Flame’s release.[6][7]
When announcing the book’s release, Yarros said it would include “politics, new adventures, old enemies and of course, dragons”.[6]
The book’s cover was released on July 8, 2024.[7] A reviewer from Today said that its dark design “signals an ominous turn in the series”.[7]
