Fourth Wing Book 4: Release Date and What We Know

When Is Fourth Wing Book 4 Coming Out?

The direct answer: nobody knows yet. Book 4 has no official title, no official release date, and no retailer listing that carries a real one. In July 2025, Radio Times noted that a Goodreads page had previously listed January 1, 2026; Yarros answered on Instagram Stories, “Let me put this rumor to rest. I love you all, but no. That release date is impossible.”

You may also see “April 2028” in fan write-ups. We could not trace that date to the publisher, the author’s website, or any retailer listing, so we do not treat it as confirmed. The same goes for any calendar-based guess for 2027 or 2028: they are extrapolations from past gaps, not announcements.

What Has Rebecca Yarros Said About Book 4?

The statements that come from Yarros herself or from major outlets quoting her:

• Five novels in total. Radio Times reports that the series is set to consist of five books, which leaves Book 4 and Book 5 after Onyx Storm.
• A contemporary novel came first. Radio Times reports that Yarros said she would turn to writing a contemporary novel for now, which fits the November 2026 release of Peculiar Stars below.
• Threshing Day is not Book 4. When she announced the collection she called it “my next book (not book four!)”.
• Writing may have started in March 2026. One fan site reports that Yarros said she began writing Book 4 that month. We could not find the original post, so treat that as reported, not confirmed.
• No title. As of this writing, neither the publisher nor Yarros has announced one.

What Is Coming From Yarros Before Book 4?

None of these is the next novel. The graphic novel retells Fourth Wing, and Peculiar Stars is a separate contemporary story.

How Long Do Empyrean Books Take?

The gaps vary too much to forecast Book 4. The only reliable signal will be an announcement from the publisher or the author.
