The Next Fourth Wing Book Is Officially Coming This Fall

Basgiath is looming in the near distance, and readers won't have long to wait to return to fantasy's most terrifying War College. Rebecca Yarros has officially announced the latest addition to her bestselling fantasy series that promises to take fans back to the world of dragon riders, and it's going to bring us something we've been waiting for since the very beginning: Xaden's Threshing Day. Sharing the announcement with fans, Yarros wrote: “Welcome to Conscription Day, Cadets! I’m thrilled to share the title and cover of my next book (not book four!) in the Empyrean series: Threshing Day! This collection contains thirteen threshing stories about some of your favorite characters and their dragons.” Yarros also teased the deluxe edition’s artwork, calling the illustrations “seriously… all so gorgeous,” before reassuring international readers to watch for release updates from their local publishers. Closing the announcement, she wrote: “I hope this gives you a fun trip back to Basgiath while I’m writing book four! So grab your leathers… The dragons are waiting!” Threshing Day goes on sale on September 29, 2026, giving Fourth Wing fans a chance to revisit Basgiath while they await the next mainline novel in the blockbuster fantasy series.
