The 3rd book in Kerri Maniscalco's Prince of Sin series!

Throne of Nightmares, the third standalone in Kerri Maniscalco's Prince of Sin series, brings together Prince Sloth—a reclusive scholar who loathes venturing beyond his enchanted library—and Lore Brimstone, a book-loving librarian whose penchant for immersive stories takes a literal turn after a mysterious caravan visit transports her into a nightmarish realm. Tasked with locating the Book of Nightmares, an artifact capable of shattering worlds and freeing the Goddess of Night, they must navigate twisted versions of Lore's favorite novels, where dark magic warps reality, betrayals lurk in every shadow, and survival hinges on outsmarting deadly games that test their wits, wills, and burgeoning connection. As the barrier between gods and mortals frays under escalating threats, Lore channels her inner heroine while Sloth confronts the perils of the heart he long avoided, racing to avert catastrophe in a tale blending perilous quests, forbidden romance, and meta-literary intrigue.
