When librarian Kassie Stillwater cracks open a dust-covered grimoire, she expects forgotten folklore, not a sinfully handsome incubus tumbling into her life.

Zarak has been imprisoned for centuries, trapped by a demon huntress who believed he was the monster she’d been hunting. All he remembers is a fierce woman with Kassie’s eyes… and a curse powerful enough to bind him for generations.

Freed at last, Zarak brings a warning: unless they destroy the enchanted book within twenty-four hours, he’ll be dragged back into its pages forever, and Kassie will fall into the hands of Rothariel—the true villain who’s been waiting for the book to open again.

With the clock ticking, temptation rising, and secrets hiding between the pages, Kassie and Zarak must unravel the past and face a dangerous attraction that may save them both…or doom them.
