Girl Who Was Supposed to Die

She doesn't know who she is. She doesn't know where she is. Just that she has to run. When Cady wakes up in a ransacked cabin, she has no memory of who she is. All she knows is that there are two men in the room and one has just instructed the other to "finish her off." Cady must find a way to save herself. But how can she do this when she doesn't even know her name?
