When Evangeline Lockwood witnesses the murder of a prominent politician, the killers will do everything they can to make sure she can't testify. Since Evangeline's father was once Deputy Director of the CIA, he knows just who to call to protect his only daughter—Atticus Cameron at Dynamis Security.

The last thing Calvin Cruz wants is to get stuck with a babysitting job, but Atticus has assigned him the task and he has no choice but to accept. There's something about Evangeline that intrigues him, but she's got secrets of her own. And the last thing he wants is to make himself vulnerable to a woman he doesn't trust. He's already had one knife in the back. He doesn't need another.
