To add insult to injury, another agent has replaced her, and a ten-million-dollar assault case is hanging over her head.

But between bumping into a college frenemy whose family business is under audit, Tara's stubborn determination to keep an eye on Nick behind the scenes, and her new long-range rifle, she's about to get a taste of just how dangerous her life can be
