The last thing recently-widowed Maggie O'Connor wants is the responsibility of a baby. But when her heroin-addict daughter, Jenna, abandons newborn Cody, Maggie discovers her own maternal instincts and love for the child prevail. Then, three and a half years later, an impeccably groomed Jenna, complete with her new, wealthy husband, Eric Vannier, returns to claim her daughter. On her first visit to Cody's new home, Maggie is horrified to find the child vacant-eyed, subdued and fearful. The police can do nothing - until an anonymous caller reveals the Vanniers' link with a sinister Satanic cult. And as an ancient prophecy turns into reality, it is all too clear that much more than Cody's sanity and safety are at stake...
