After her best friend is brutally murdered by a stranger she met one night in a country bar, Marli McKinnon feels grief-stricken and horribly responsible. Driven by guilt, she returns to Cactus Jack's Saloon, hoping to encounter the man she knows as Ron, not sure what she's going to do if she sees him. Instead she meets another stranger - a big, gorgeous man with whom she shares a surprising connection, and to whom she's unwillingly attracted.
Six months ago, FBI Special Agent Trey Nicholson's life was ripped apart by betrayal, which sent his life spiraling into the biggest screw-up of his career. He's intrigued by the pretty, sad-eyed blonde he meets at Cactus Jack's, and curious about what she's doing there all alone. When Marli learns he's an FBI agent, she asks for his help. She tells him the story of her friend's murder and Trey realizes with horror that the serial killer he let get away has killed again.
Each motivated by guilt, Trey and Marli work together to try to find the killer before he kills again...before he kills Marli...
