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 paediatrician 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. And unless Sara and Jeffrey can uncover the deadly secrets the children hide, it's going to happen again...
