Annie Gallagher has made a new life for herself after leaving her job as a covert operator in Europe. She now lives for her son, keeping under the radar while making a home in the Colorado Rockies. Her past catches up to her during a snowstorm when her son is kidnapped and a phone call she receives tells her what she must do before she can get him back. Annie doesn't have a choice; to save her son, she must do the job they have requested and she must do it alone -- she is no longer part of a team. Unbeknownst to Annie, other forces receive Intel of her involvement and move to stop her. She still has the necessary skills to complete the mission, but Annie is attacked while doing surveillance on her target, bringing her face-to-face with the man she thought she left behind.

Nash Brennon is no longer an operative in Europe; he is now a member of the American Tactical Intelligence Command (A- Tac) with a tenured professorship specializing in history and espionage. His team has just received Intel that his ex- lover and teammate has been hired to assassinate a government official. Their job is to stop her and find out who commissioned her for the job. Nash is suddenly taken back to when Annie disappeared, and left wondering why, after all this time, she's decided to become one of the bad guys. Once he gets his hands on her, Annie is hostile like he is the one who left her bleeding to death. But as she fights him for her life, he can't help but wonder if something else is going on.

Dee Davis has given her new series a hot one-two punch with mind-blowing action and enough intrigue to keep you from putting this book down. I am looking forward to learning about the rest of the A-Tac team.
