Saturday night dates at the skating rink have been a tradition in the small southern town of Heartsdale for as long as anyone can remember, but when a teenage quarrel explodes into a deadly shoot-out, Sara Linton -- the town's pediatrician and medical examiner -- finds herself entangled in a terrible tragedy.What seemed at first to be a horrific but individual catastrophe proves to have wider implications. The autopsy reveals evidence of long-term abuse, of ritualistic self -mutilation, but when Sara and police chief Jeffrey Tolliver start to investigate, they are frustrated at every turn.The children surrounding the victim close ranks. The families turn their backs. Then a young girl is abducted, and it becomes clear that the first death is linked to an even more brutal crime, one far more shocking than anyone could have imagined.
