1. Fourth Wing
by Rebecca Yarros
Book 1 of Empyrean. Non-negotiable — Iron Flame doesn't work without it. Read Fourth Wing first, then come back. Every r/Romantasy reader's entry point to Yarros.
Iron Flame is Rebecca Yarros's 2023 sequel to Fourth Wing — book 2 of the Empyrean series. Violet Sorrengail survived her first year at Basgiath. Now everything she thought she knew about the war, about Xaden, about the kingdom itself is revealed to be a lie. The book that broke r/Romantasy when it dropped — bigger stakes, darker political reveals, and a slow burn that doesn't let up. Read Fourth Wing first.

Book 3 of Empyrean, released 2025. The continuation of Violet and Xaden's story. If Iron Flame wrecked you, Onyx Storm is next — pre-order territory for the entire fandom.
by Sarah J. Maas
Feyre Archeron, a mortal huntress, is dragged into the enchanted fae lands after killing a wolf — and pulled into a world of dangerous courts, dark magic, and a love that will unmake and remake her. The romantasy foundation Yarros builds on. The most-recommended Empyrean readalike on r/Romantasy.
by Sarah J. Maas
An assassin competes to become the king's champion. Same Maas universe-adjacent intensity that Yarros readers gravitate toward — military training, political stakes, slow-burn romance.

The 2024 romantasy breakout — fae warrior, deadly bargain, 700 pages of unrelenting tension. The book Iron Flame fans pick up while waiting for Onyx Storm.
by Jennifer L. Armentrout
The blueprint for the romantasy formula Yarros perfected. A sheltered Chosen falls for her dangerous guard. Same scale, same spice, same slow burn.
Yes, absolutely. Iron Flame is a direct continuation — it starts roughly where Fourth Wing ended and assumes you know every character, every relationship, every political faction. Skipping book 1 will spoil the best twists and ruin the emotional payoff.
r/Romantasy is split. Most readers agree Iron Flame is heavier, slower in the middle third, and emotionally darker. The payoff in the last 100 pages is often called the best of the series so far. Reread Fourth Wing first if it's been a while.
Onyx Storm (book 3 of Empyrean) released January 2025. Book 4 is announced. The series is planned for 5 books total. The wait between books is real, which is why the r/Romantasy community devours every book on release weekend.
