Don't Look Back — Christie Craig

New York Times bestselling author Christie Craig's thrilling romantic suspense about a by-the-book FBI agent who must trust a risk-taking detective for help tracking down her sister's killers.
FBI agent Bree Ryan's latest mission is personal. She's posing as a waitress at the Black Diamond strip club, the same club where her estranged half sister worked until she turned up dead. When Bree's undercover assignment is compromised, she turns to the only man she knows who can help her: Connor Pierce, a too-sexy-for-his-own-good, rule-breaking cop with a knack for solving cold cases.

When someone breaks into Bree's apartment, Connor's detective skills aren't the only things that kick into overdrive. Although his job demands he remain detached, now he finds himself tempted not only by Bree's beauty but also her intelligence and bravery. As the investigation -- and their attraction -- grows more intense, lives are in jeopardy, and Connor finds the most important rule he must break is his own. But can he put his heart on the line?
