The Next Fourth Wing Book Is Officially Coming This Fall

Author Rebecca Yarros has announced a new companion volume to her bestselling Empyrean series titled Threshing Day, which is scheduled for release on September 29, 2026. This book is a short-story collection rather than the anticipated fourth novel, offering thirteen distinct perspectives on the brutal ritual where dragons select their riders. The publication features sixteen color illustrations and includes highly sought-after backstories, such as Xaden Riorson’s experience during the event. While the author continues working on the official fourth installment, this addition serves to expand the lore and deepen the history of beloved side characters. It provides a strategic bridge for the fandom, maintaining momentum for the franchise while the main narrative remains in development. This release underscores the cultural dominance of the romantasy genre and the massive commercial success of the series.
