Dr. Ellie Sullivan has witnessed the shooting of an FBI agent in pursuit of a ruthless modern-day Bonnie and Clyde. The only person to see the shooter's face, Ellie is suddenly thrust into the center of a criminal investigation spearheaded by the no-nonsense, by-the-book, and tantalizingly handsome agent Max Daniels.

When the couple is captured, she'll be called to testify. But the Landrys have been caught before, and each time the witnesses are scared into silence--or they disappear. Now Max vows to be Ellie's shadow, promising never to leave her side until the trial. But that could be dangerous for both of them, and it isn't long before the sparks--and the bullets--fly.
