‘Fourth Wing’ Fans Rejoice: Rebecca Yarros Has a Surprise Book Coming This Fall
We still might not have a lot of information on when exactly Fourth Wing book four will be hitting bookstores, but thanks to author Rebecca Yarros, we do know that later this year there will be a new book in The Empyrean series that’s actually not book four!
To learn more about this mystery book, including details on what it could be and when you can expect to get your hands on it, keep reading!
What we know so far about Rebecca Yarros’ next book
In March, Yarros teased book 4 on Instagram, telling readers, “I’m back writing in the Empyrean world for the foreseeable future. Let’s ride.”
Then, on Saturday, April 18, Yarros was back on Instagram, sharing that her untitled Empyrean novel had hit number one on the Amazon bestseller list, despite the fact that it hasn’t officially been announced yet. She also shared a little bit more about what the novel was going to be about, writing “this hasn’t altered book 4’s timeline in the least…This is NOT the upcoming graphic novel.”
“Okay, so I had this little idea about a year ago to drop a surprise for you guys. But then you not only found it as soon as my publisher put it on preorder, but shot it straight to number one on Amazon without a cover, title, or even a vague idea of what might be coming your way!?!? You’ve rendered me speechless,” the author continued. “Surprise has been the goal, but I can’t sit here silently and not tell you how thankful I am for you. How utterly overwhelmed I am by the continuous love this community gives. Please know that I never take your enthusiasm and dedication for granted. I know how rare this air is. You are a constant source of joy not just in my life but each other’s, and gratitude doesn’t begin to describe how I feel about this community.”
What will the new Empyrean book be about?
Thrilled fans have been speculating online, tossing around ideas about the plot. Some think it will be a full copy of Major Afendra’s Guide to the Riders Quadrant (Unauthorized Edition), which is heavily quoted at the beginning of several chapters throughout the series. Others think it could be a prequel about Violet’s father or even the history of the dragons.
“I really hope it’s Tairn’s [one of Violet’s dragons] autobiography,” one person commented on Yarros’ post.
“I have a feeling it’s Andarna’s [Violet’s other dragon] diary rants about Tairn tbh,” another one commented.
And then of course, despite Yarros confirming that it is not book four, some readers are speculating it could be more of a 3.5 situation, offering up some details that were left out of book 3, Onyx Storm. That theory was further confirmed after readers learned the new book is only 176 pages, which is about 400 pages shorter than the other books in the series.
“176 pages,” commented one reader. “That could be just long enough of a novella to explain those 12 hours that Violet was missing.”
When will the new Rebecca Yarros book be released?
The untitled Empyrean novel will be released on Tuesday, September 29, 2026. You can pre-order it now wherever books are sold.
“This one is for you guys,” Yarros wrote. “I hope you love it as much as I’ve loved writing it.”
