.
As a mother, Rebekah "Max" Maxfield had no choice. She could either leave her daughter in the hands of an abusive father--or hide her away and face the legal consequences. She decided to save her daughter. But she was caught. Charged. Convicted. And imprisoned.Now Max will do anything to get out of jail--even play along with the feds. With her experience in electronic surveillance, she's the perfect choice for an FBI undercover operation. If Max accomplishes her mission--and exposes a company's corruption--she'll be given a chance to start a new life with her daughter. But the game has two rules they never told her about.
The players will kill to win.
Her daughter is the pawn.
