What readers think

Readers consistently praise the romantic payoff — Kane's groveling redemption arc and the long-awaited spicy scenes are highlights most reviewers celebrate. The fast pace, expanded world-building (especially the underwater Citrine kingdom), and sharp banter between leads also earn regular acclaim. Secondary character dynamics, particularly the friendship between Arwen and Mari, are singled out as a series strength. Critics note that Arwen's emotional responses can feel immature or inconsistent — readers sometimes find her willingness to hurt Kane petty rather than sympathetic. A few reviews flag the love triangle with Halden as a weak addition that doesn't create genuine tension, and the cliffhanger ending, while thrilling to some, frustrated others.

Read it if

  • · Readers who fell for Kane in book one and want the slow-burn payoff and groveling redemption arc
  • · Romantasy fans who enjoy quest-driven sequels with expanding kingdoms, political intrigue, and ensemble casts
  • · Readers who loved A Court of Mist and Fury's pattern of betrayal → earned forgiveness → elevated spice

Skip it if

  • · You haven't read A Dawn of Onyx — this is a direct sequel and requires the first book
  • · Love triangles frustrate you rather than add tension
  • · You prefer emotionally mature heroines — Arwen's processing of the betrayal reads young to some readers

If you liked this

  • · For fans of A Court of Mist and Fury — same betrayal-to-forgiveness arc with a morally grey king and escalating spice
  • · Like From Blood and Ash but with a healer heroine on a sea voyage quest with higher fantasy world-building
  • · For fans of Fourth Wing — action-heavy romantasy with a fierce heroine, prophecy stakes, and steamy payoff
  • · Fans of Throne of the Fallen who want enemies-to-lovers in a lush multi-kingdom fantasy setting
