Emily & OIiver by Robin Benway

​Emmy just wants to be in charge of her own life. She wants to stay out late, surf her favorite beach — go anywhere without her parents’ relentless worrying. But Emmy’s parents can’t seem to let her grow up —not since the day Oliver disappeared. He’d thought, all these years, that his dad was the good guy. He never knew that it was his father who kidnapped him and kept him on the run.
