"He is psychologist and criminal profiler Dr. Tony Hill's worst nightmare--a killer driven by the most perverted hungers and unmoved by youth and innocence, a killer with a long shopping list of victims who leaves no trail. The murder-mutilation of teenager Jennifer Maidment is horrific enough on its own, but Hill quickly realizes that it's just the beginning of a chilling campaign targeting an apparently unconnected group of young people--victims that the monster has been grooming through a social networking site. It is a case that is reawakening ghosts of Tony Hill's past. And the longer it takes to uncover a motive and a maniac, the more innocent youth will die"--Cover, p. 4.
