Chicago's top undercover cop, Cal Black, has faced his share of danger, but he's never tangled with 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. What she is looking for is her little sister…and Deme is determined to find her without Cal's expertise. The other Chattox sisters—and their mystical powers—are all the help she needs. That is, until they unearth a terrifying secret buried deep underground—and Deme finds herself possessed by a desire that threatens to destroy her.
