The Empyrean Books Explained: Reading Order and What to Know
The Empyrean series by Rebecca Yarros starts with Fourth Wing, continues with Iron Flame, and expands in Onyx Storm. The books should be read in order because the romance, war, dragons, and political reveals build directly from book to book. Three of five planned books are published. This guide covers the reading order, what each book is about (without spoilers), and what to expect.
Fourth Wing (Book 1, 2023)
The setup. Violet Sorrengail enters the Riders Quadrant.
Violet was supposed to be a scribe. Her mother, a commanding general, forces her into dragon-rider training instead. Bond with a dragon or die. The romance with Xaden Riorson builds through genuine conflict.
Iron Flame (Book 2, 2023)
The escalation. Trust nothing you learned in book one.
Everything Violet thought she knew about the war, the wards, and the people around her is challenged. The scope expands beyond the academy. Ends on a major cliffhanger.
Onyx Storm (Book 3, 2025)
The midpoint. The war goes continent-wide.
The third of five planned books. Expands the war, the mythology, and the romantic stakes. Two more books are expected.
What to know before starting
Explicit sexual content, graphic violence, and characters dying in harsh ways. This is adult fantasy romance, not YA, despite the academy setting.
Five books planned. Three published. Yarros writes quickly. Expect roughly one book per year.
