As a forensic investigator for the Cleveland Police Department, Maggie Gardiner has seen her share of Jane Does. The latest is an unidentified female in her early teens, discovered in a local cemetery. More shocking than the girl's injuries for Maggie at least is the fact that no one has reported her missing. She and the detectives assigned to the case (including her cop ex-husband) are determined to follow every lead, run down every scrap of evidence. But the monster they seek is watching every move, closer to them than they could possibly imagine.
