The September Sisters by Jillian Cantor

The last conversation 13-year-old Abby had with her little sister Becky was a fight in their backyard pool. That night, Becky was taken from her room while she slept and Abby woke up to find police officers in her kitchen. As the police try to find out what happened to Becky, Abby watches as her life falls apart: her mom becomes depressed and stays in bed for weeks at a time; her dad becomes incredibly overprotective, making their home into what Abby calls a prison that keeps people out instead of in; and her best friend suddenly stops talking to her. But then Abby becomes friends with Tommy, the boy who moves in next door. Together they try to find Becky's kidnapper and help each other get through the unfortunate events that have happened in their lives. The September Sisters is a moving tale of love and survival that will appeal to both adults and teens.
