Darkness has broken into the Realm of Four Kingdoms, and the fox spirit who has always fought for it fears she could end it. Jayci Lee closes her romantasy series with Sunny's last stand.

Readical Key Points

• Book three and the finale of the Realm of Four Kingdoms series, according to the publisher.
• Epic romantasy centered on Sunny Cho, a fox spirit, and Ethan, ruler of the Kingdom of Mountains.
• Hardcover from Montlake, published April 14, 2026; 443 pages.
• Content note: explicit sexual content and battle violence.

Sunny has won every fight so far and believed she stood on the right side of them. Then an endless darkness breaches the realm and threatens every living thing, and her power might be the one thing able to stop it, or the thing that wrecks the realm by accident. She takes the fight across the kingdoms, but Ethan's Kingdom of Mountains is the one front she is forbidden to enter. As old prophecies play out and the gods' secrets surface, the two are pulled between duty and desire.

This Montlake hardcover suits romantasy readers who like a sharp-tongued heroine and a love story tested by fate. Light Burned ties off threads from the earlier books, which makes it the last stop in the series rather than the first.
