For Samantha Kelleher careening around a NASCAR track is treacherous enough, especially after the near-death experience that left her burned, broken, and guilty. When the top team's drivers start to die from engine sabotage, the cop who is assigned to investigate turns out to be the sexy stranger Sam slept with to get revenge on a cheating ex. At least that's what she told herself.

Drew isn't going to let another cop, or civilian for that matter, die on her watch. Can they catch the real killer before their chance at a future goes up in flames?
