Romantasy · Reading guide
🐉 Fourth Wing (The Empyrean)
Violet Sorrengard trained her whole life to be a scribe. Instead her mother orders her into Basgiath War College, where dragon riders bond or die, and where the wingleader with every reason to kill her is impossible to stop watching. Dragons, war, and a slow burn that scorched its way to the top of every chart.
Fourth Wing is the book that put "romantasy" into everyday vocabulary. Rebecca Yarros's Empyrean series follows Violet Sorrengard, brittle-boned and built for the scribe's quadrant, forced instead into a war college where the entrance exam is a parapet you can fall off and the classmates are allowed to kill you.
Three books are out: Fourth Wing, Iron Flame, and Onyx Storm, which had the biggest opening week of any adult novel in two decades. Book 4 is being written now, and a war-college anthology called Threshing Day arrives September 29, 2026.
Is Fourth Wing (The Empyrean) on Kindle Unlimited?
Yes, and this surprises people: Fourth Wing, Iron Flame, and Onyx Storm are all in Kindle Unlimited as of July 16, 2026. A lot of older articles still say the series is not on KU, and they are out of date. At $14.99 per ebook, reading all three inside a KU trial is the single best value on this page.

Amazon greenlit the TV series
Prime Video ordered Fourth Wing straight to series in May 2026, produced by Michael B. Jordan's Outlier Society with Lisa Joy directing the pilot and Meredith Averill as showrunner. Casting news will start the next hype wave, and hype waves have a way of ending KU availability for adapted series.
While you wait for book 4 (2027 at the earliest, per Yarros), the Threshing Day anthology lands September 29, 2026 and is available for preorder now. Preordering locks today's price and it delivers automatically on release night.
The audiobook angle
The audiobooks feature dual narrators and are a huge part of the fandom. All three are on Audible, and an Audible trial covers the first one free.
