TL;DR
The Empyrean series continuation (the next book after Onyx Storm) is the right purchase for readers invested in Rebecca Yarros's Fourth Wing-launched romantasy phenomenon. The Empyrean series — Fourth Wing, Iron Flame, Onyx Storm, and continuing — is one of the most-popular contemporary fantasy-romance series of recent years. Dragon-rider academy setting, complex magic system, and the slow-burn romance that BookTok has championed. For fans who finished the prior books, this is the next entry; for new readers, start with Fourth Wing first.
Why It Matters
Rebecca Yarros's Fourth Wing (2023) launched a publishing phenomenon — selling millions, dominating BookTok, and reshaping contemporary romantasy expectations. The Empyrean series became the foundational text for the post-Fourth Wing romantasy boom. Each book continues the dragon-rider Violet Sorrengail's arc through the academy and beyond. Reading the series in order is the right approach.

Who It's For
Fans who finished Fourth Wing, Iron Flame, and Onyx Storm. BookTok-aligned readers. Romantasy enthusiasts. Skip it if you haven't read the prior books (start with Fourth Wing first), if you don't enjoy fantasy-romance hybrids, or if dragon-academy settings don't appeal.
How to Use It
Read in series order: Fourth Wing → Iron Flame → Onyx Storm → this continuation. Don't read out of order — character arcs and world-building build sequentially. The audiobook dual narration handles the dragon-rider perspectives well. Discuss with BookTok community for full cultural context.
How It Compares
Vs. Fourth Wing alone: this is continuation, not entry point. Vs. Iron Flame: comparable Empyrean continuation. Vs. A Court of Thorns and Roses by Sarah J. Maas: Maas is comparable romantasy tier. Vs. The Cruel Prince by Holly Black: Black is YA fantasy with romance. Vs. Throne of Glass by Maas: comparable extended-series romantasy.
Bottom Line
The right Empyrean continuation for invested Fourth Wing fans. Buy it for the next entry. Skip it without reading the prior books or for non-romantasy readers.
