Identical
Ellen Hopkins
 From the bookjacket "Kaeleigh and Raeanne are 16-year-old identical twins, the daughters of a district court judge father and politician mother running for Congress. Everything on the surface of their lives seems Norman Rockwell perfect, but underneath run deep and damaging secrets. Kaeleigh is the good girl-her father's perfect flower, something she has tried so hard to be since she was nine and he started sexually abusing her. She cuts herself and vomits after every binge, desperate to feel something normal. Raeanne uses painkillers, drugs, alcohol, and sex to numb the pain of not being Daddy's favorite. Both girls must figure out how to become whole, but how can they when their world has been torn to shreds?"
