The Devil You Know — Robert Swartwood

Javier Diaz is dead. Holly Lin knows this because she killed Javier and his men. Now, to protect her family, Holly must travel to Mexico to take out Javier's father before he learns about the death of his son. It should be a simple mission, but nothing is ever simple for Holly Lin. The plan is to take out everybody in the Diaz compound -- until she encounters a woman and two children hiding inside. Suddenly, the night is only beginning. And by the end, Holly will come face to face with a new kind of evil -- one that she will have no choice but to defeat.
