Fourth Wing graphic novel
Unnumbered in seriesCompanion
ConfirmedGoes on sale 6 Apr 2027
The first volume of a stunning graphic novel edition of the #1 New York Times bestselling phenomenon Fourth Wing, adapted by Rebecca Yarros herself! Enter the brutal and elite world of a war college for dragon riders as you’ve never seen it before…
Rest of description
Twenty-year-old Violet Sorrengail was supposed to enter the Scribe Quadrant, living a quiet life among books and history. Now, the commanding general―also known as her tough-as-talons mother―has ordered Violet to join the hundreds of candidates striving to become the elite of Navarre: dragon riders.
But when you’re smaller than everyone else and your body is brittle, death is only a heartbeat away...because dragons don’t bond to “fragile” humans. They incinerate them.
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.
Friends, enemies, lovers. Everyone at Basgiath War College has an agenda―because once you enter, there are only two ways out: graduate or die.
Lavishly illustrated with breathtaking full-color artwork, this stunning graphic novel, adapted by Rebecca Yarros herself, features the first half (chapters 1 through 22) of the #1 New York Times bestseller Fourth Wing, bringing you into the world of the Empyrean series like never before!
