  2. Throne of Secrets

    Novel
    Throne of Secrets followed Throne of the Fallen in 2024, its 520 pages the longest of Kerri Maniscalco's Prince of Sin trilogy so far. Set in the same demon-court world as her Kingdom of the Wicked trilogy but centered on a different Prince of Hell and a new heroine, it continues the adult-romantasy spinoff's higher heat level and standalone structure, ahead of Throne of Nightmares centering Prince Sloth.

About the Prince of Sin series

Set in the same demon-court world as Kerri Maniscalco's Kingdom of the Wicked trilogy, Prince of Sin steps away from Emilia and Wrath to give each of the seven Princes of Hell his own book and his own dangerous romance. Throne of the Fallen opens the spinoff with a fresh heroine and a new prince, trading Emilia's revenge-driven arc for a stand-alone story that still trades in the same sensory, food-and-magic-soaked world of Hell's court politics. Throne of Nightmares, the third entry, centers Prince Sloth -- happiest buried in his enchanted library -- who is forced out into a new realm to hunt down the world-breaking Book of Nightmares alongside a heroine drawn into the search.

Marketed as Maniscalco's adult-romantasy debut (spicier and more explicit than the Kingdom of the Wicked trilogy's young-adult register), the series keeps the morally grey demon love interests and lush worldbuilding that made the original trilogy a hit, while giving each entry a different pairing and a more standalone structure than Kingdom of the Wicked's single continuous plot.

For readers who finished Kingdom of the Wicked wanting more time in Hell's court -- with new romances, new princes, and a higher heat level -- this is the direct follow-on series.
