Possessed (The Thorne Trilogy #2)

Calling a Demon forth wasn't the wisest thing the Ayers witches have ever done. For centuries, the Ayers have been slaves of the Demon Lilith, one Ayers witch destined to do her will while another was sacrificed to the Hunters. But Monroe Jacobs has changed the rules ... A witch from the Ayers line, Monroe's powers have always been connected to Demons and now she knows why. Once a slave to Lilith, she has thrown off her blood ties to the Demon queen by calling on her son, the hybrid-Demon, Luther. Now Monroe must discover what it means to be a witch while fighting off demonic possession. For Luther "Thorne" Craig, his attraction to the witch, Monroe, isn't just a complication, it's a distraction. He's always been happy with his life, serving the denizens of Hell while living flamboyantly, but now he's declared war on his mother and Lilith won't rest until she sees him dead. Armed with her own book of shadows, Monroe is dragged into a civil war between mother and son while Luther fights his demonic need to truly possess her.
