Ruth Carver has always competed like her life depends on it. Ambitious. Tough. Maybe even mean. It's no wonder people call her Ruthless. When she wakes up with a concussion in the bed of a moving pickup truck, she realizes she has been entered into a contest she can't afford to lose.

At a remote, rotting cabin deep in the Blue Ridge Mountains, Ruth's blindfold comes off and she comes face-to-face with her captor. A man who believes his mission is to punish bad girls like Ruth. A man who has done this six times before. The other girls were never heard from again, but Ruth won't go down easy. She escapes into the wilderness, but her hunter is close at her heels. That's when the real battle begins, and Ruth must decide just how far she'll go to survive.
