Night Mischief (Nocturne, Book 16) by Nina Bruhns
A deal with the Devil?
Dawn never imagined that a thoughtlessly spoken spell could conjure up her worst nightmare - a seriously sexy demon. Yet Galen could help Dawn earn her father's respect. In exchange for a long-lost diamond that her father has been searching for his whole life, Dawn will spend five nights in the sinfully handsome demon's bed.
Little does Dawn know that Galen's real objective is to weave his own brand of justice. But then the sinister net he has woven traps his most unsuspecting victim - himself. Could falling for Dawn be his undoing?
Between the mortal and the paranormal realms lie... DARK ENCHANTMENTS
