If you’re wondering whether Onyx Storm lives up to the hype, this spoiler-free review breaks down what works, what might not, and why it’s dominating bookish conversations.


Quick Synopsis (No Spoilers)

Following the emotionally devastating events of Iron Flame, Onyx Storm throws readers deeper into the chaos of the Basgiath War College and its crumbling political landscape. Violet Sorrengail must grapple with grief, rebellion, and revelations that shake her understanding of who the real enemy is.

More dragons, higher stakes, and soul-searing romantic tension keep readers hooked from the first page to the final cliffhanger.

What Makes Onyx Storm review a Must-Read

1. World-Building That Expands

Yarros expands the Empyrean universe, introducing new territories, magical mechanics, and complex alliances. The lore around dragons, wards, and relics is rich without being overwhelming.

2. Deep Character Growth

Violet is more than just a chosen one. She’s wounded, brave, and constantly evolving. Supporting characters like Xaden, Rhiannon, and Andarna also get meaningful arcs.

3. Romance with Real Stakes

The romantic tension between Violet and Xaden simmers with both passion and pain. Their relationship is messy, mature, and magnetic—exactly what romantasy readers crave.

4. Relatable Mental Health Themes

Yarros deserves praise for her nuanced portrayal of trauma, PTSD, and the emotional toll of war. These elements add realism and depth to the fantasy narrative.

What Might Not Work for Everyone

  • Lengthy exposition: At over 500 pages, some sections feel padded with internal monologue and slower pacing.
  • Requires prior reading: New readers should start with Fourth Wing to fully understand the stakes and character dynamics.
  • Cliffhanger alert: Be prepared for an ending that demands the next book.
