I could not put this book down.
Alex is a social worker whose job is to help abused children. One day in the park she runs into a little 3 year old girl, who does not talk. Her father comes over and Alex has a feeling things are not right. Later she comes across the little girl again, this time as a child she has to determine is she is being abused.
Alex has her own past. Her father killed the rest of her family and she was adopted into anohter family with a brand new name. She spent her childhood in hiding due to authorities being afraid that her father would still come after her. She finds out her mother did not die that day in the attack and comes back to explain Alex's history and why her mother could not come out of hiding herself.
