Twenty years ago, four teenagers at summer camp walked into the woods at night. Two were found murdered, and the others were never seen again.

For Cope, the county prosecutor of Essex, New Jersey, mourning the loss of his sister has only recently begun to subside. Cope is now dealing with raising his six-year-old daughter as a single father after his wife has died of cancer.

Balancing family life and a rapidly ascending career distracts him from his past traumas, but when a homicide victim is found with evidence linking him to Cope, the well-buried secrets of the prosecutor's family are threatened. Is this homicide victim one of the campers who disappeared with his sister? Could his sister be alive? Cope has to confront so much he left behind that summer twenty years ago.
