A killer with a penchant for torture has taken notice of forensic expert Gwen Marcey . . . and her daughter.

When Gwen Marcey's dog comes home with a human skull and then leads her to a cabin in the woods near her Montana home, she realizes there's a serial killer in her community. And when she finds a tortured young girl clinging to life on the cabin floor, she knows this killer is a lunatic.

Yet what unsettles Gwen most is that the victim looks uncannily like her daughter.

The search for the torturer leads back in time to a neo-Nazi bombing in Washington state-a bombing with only one connection to Montana: Gwen. The group has a race-not-grace model of salvation . . . and they've marked Gwen as a race traitor.

When it becomes clear that the killer has a score to settle, Gwen finds herself in a battle against time. She will have to use all of her forensic skills to find the killer before he can carry out his threat to destroy her-and the only family she has left.
