The search for a missing Chicago sorority initiate reunites a cop with his bewitching ex in this paranormal romance by a New York Times–bestselling author.

Undercover cop Cal Black has never encountered the paranormal . . . until now. His mission is simple: to investigate the disappearance of a sorority girl from a private college. But there are two complications: the girl's a witch, and her sister is the enchantress who broke his heart.

Deme Chattox isn't looking for a man. Especially a bad boy like Cal—even though every inch of her body remembers the magic of his touch. She's determined to find her little sister without Cal's expertise. That is, until they unearth terrifying secrets buried deep in the underground that threaten to destroy her.
