Don’t Look Back by Christie Craig

FBI agent Brie 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 Brie’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 Brie’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 Brie’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?
