Unfinished Business! A killer was loose in Colorado, and evidence specialist Cassie Dumont was determined to prove her expertise to the skeptical local cops. So the arrival of FBI agent Seth Varitek, a man she'd clashed with before, didn't sit well with her competence, her ego--or her libido. The last time they'd crossed paths, Seth saw just how close Cassie got to a violent criminal. His refusal to confront that fear again convinced him to keep the feisty criminologist at arm's length. Before long, working together became an exercise in torture--especially once the murderer they were tracking made Cassie his next target.
