Abducted (Lizzy Gardner #1)
T.R. Ragan

Fourteen years later, Lizzy is a licensed PI known as the 'one who got away'. When she's not searching for runaway teenagers, working on insurance scams, or talking to her therapist, she's at the local high school teaching young girls to defend themselves. But her world is turned upside down for the second time after she receives a call from Jared Shayne. He's an FBI special agent now and he needs her help. Lizzy has no plans to get involved. Not until Jared tells her the kidnapper left her a personalized note.
