Seventeen-year-old Charlotte barely escaped from her abusive parents. Now she's trying to start a new life, but while she can erase her former identity, she can't rid herself of the memories. And her troubled history won't let her ignore the little girl she sees in the park. The girl with the bruises and burn marks. That's when Charlotte begins to receive the threatening notes left in her apartment - without a trace of entry. As the messages grow more menacing, she doesn't just need to uncover who is leaving them; she needs to stop whoever it is before anyone else she loves ends up dead.
