The day after Burning Lake's notorious, debauched Halloween celebration, Detective Natalie Lockhart uncovers a heartbreaking scene - a young woman, dead and lying in a dumpster. There's no clue to who she is, save for a mystifying tattoo on her arm, and a callus underneath her chin. She's not from around here. No one knows who she is.

As Natalie retraces the young woman's steps leading up to her death, she uncovers even more horror - a string of murders and disappearances, seemingly unconnected, that may have ties to each other - and explain the abrupt disappearance of her best friend years ago.

As Natalie digs deeper to find the killer, old hurts are renewed and dark secrets uncovered. But deep within the mind of the hunter is a darkness Natalie could never have imagined, and as she draws closer to the truth, the killer is weaving a trap for her that may prove unescapable.
