BookTok fans, this isn't a drill: Rebecca Yarros has started working on Fourth Wing book 4! A couple weeks ago (on January 23, 2026, to be specific), Yarros shared that she was getting close to starting the fourth book in the series and that time has finally arrived. "In the next few (hopefully couple) weeks, I’ll be back in the Empyrean world for the foreseeable future!" she says on Instagram. "Book 4’s playlist is simmering and I’m almost ready for the index cards and plot board. Don’t worry, everyone in Navarre is still alive. For now. 😉"
I've done all the research and compiled everything you need to know about the Empyrean series' next installment so that you can focus on what's important: rereading all the Fourth Wing books until the new one hits shelves ;).
Keep reading for the latest update on the Empyrean series and Fourth Wing book 4.
What is the plot of Fourth Wing book 4?
Amazon
Okay so there's no real answer to this question yet because yesterday, February 8, Rebecca Yarros shared that she started plotting for the Fourth Wing series' book 4. So the author herself doesn't even know the plot yet! "Feels like a great day to start a stack of index cards. 😉" she says on Instagram.
But (spoiler!!) at the end of Onyx Storm, everyone finds out Xaden is venin which means he now has a huge target on his back. So, yeah, book 4 is sure to have some major drama from the very beginning.

Producer (and Oscar winner!) Michael B. Jordan recently gave an "unexpected" update on the Fourth Wing show:
“We are making sure that this is going to be a exciting show that delivers on all of the things the fans want and some of the things that they won’t be expecting either,” he said in an interview with Deadline. “But trust me, I know how beloved this franchise IP is and we’re diligently…We’re in the lab; we’re cooking up. We got it. It’s coming. It’s early stages, but I feel how much people care about this one. It’s not lost on us.”
