They say to keep your friends close, and your enemies closer . . .

Hostage Negotiation Team member Bart Gutierrez is shocked to find Lucy Aguayo, a girl he knew as a teenager, working for the deadly Castillo drug cartel. This revelation uncovers a secret in Bart's family so big it forces him to accept a dangerous offer: infiltrate the cartel to keep his family safe. Once inside the cartel's headquarters he discovers that a large-scale attack on America is imminent and the only way to prevent it is to bring Lucy in on his plans—-and hope she doesn't betray him.

Lucy Aguayo has become a key player in the Castillo cartel, but not for money or power—-she's on a mission of vengeance for her father's murder. Just when she gets a chance to bring down the cartel leader responsible, Bart Gutierrez appears, stirring up buried feelings and disrupting all her plans. But as the enemy closes in from all sides, Lucy must choose between being free from her past or finding justice for it. Can she give up everything she's ever worked for?
