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.
