Delaney Murphy has always known she's the Devil's daughter. And although the title itself is a burden, she never expects to inherit all her father's infernal abilities. When her newfound magic begins to poison the people closest to her, Laney must make a choice. To protect the world from the worst she can do, she leaves everyone she loves behind and builds a new life for herself, alone, in a place where she can control the urge to give in to the magic living within her. But when she recognizes a familiar pattern in a string of murders, Laney leaves her peaceful, isolated life behind and goes on the hunt, unleashing a threat she never dreamed possible. Confronting this menacing specter could mean giving in to temptation and becoming the one thing she fears most. Will she use her magic to do the right thing, even if it means hurting the ones she loves?
