Yarros‘ 2023 New York Times bestseller The Fourth Wing is part of the author‘s The Empyrean book series, which also includes installments Iron Flame (2023) and Onyx Storm (2025). Yarros has a five-book series planned and has teased that she’s writing the fourth book. Titles and release dates for the planned fourth and fifth books have yet to be announced.

The story follows 20-year-old Violet Sorrengail whose plans for a quiet life are upended when her mother, a military general, orders her to join the brutal Basgiath War College and become one of several hundred candidates vying to become dragon riders. Prime Video ordered the series in May after

The book’s synopsis further reads: “With fewer dragons willing to bond than cadets, most would kill Violet to better their own chances of success. The rest would kill her just for being her mother’s daughter—like Xaden Riorson, the most powerful and ruthless wingleader in the Riders Quadrant. She’ll need every edge her wits can give her just to see the next sunrise. Yet, with every day that passes, the war outside grows more deadly, the kingdom’s protective wards are failing, and the death toll continues to rise. Even worse, Violet begins to suspect leadership is hiding a terrible secret.“

The story also follows the romance of enemies-turned-lovers Violet and Xaden.

Amazon MGM acquired rights to Yarros‘ book series in 2023 and began developing it with Michael B. Jordan’s Outlier Society, which has an overall series deal with the studio. Locke & Key co-creator Meredith Averill took over as showrunner in September 2025 after original showrunner Moira Walley-Beckett exited.

Averill is executive producing with Jordan and Elizabeth Raposo for Outlier Society; Yarros; Jonah Nolan, Lisa Joy and Athena Wickham of Kilter Films; and Liz Pelletier and Sherryl Clark of Premeditated, Entangled Publishing’s sister company. Stefano Agosto, executive vp television at Outlier Society, is a co-EP.
