Abducted and hidden away deep in the Rocky Mountains, Susan Bell is frantic to escape her murderous captor.

Freshman Special Agent Burke Cameron is straight-laced, traditionally minded, and comes with a hefty set of old-fashioned values. Burke doesn't know what to do with the free spirited, progressive woman he's falling for. He and Susan don't want any of the same things and he knows he should move on, but he can't seem to resist her.

Burke and Susan's world views are polar opposites and a lasting future together is impossible to imagine. But when a group of six women, including Susan, goes missing in the Colorado Rockies, their differences fall away, and all that matters to Burke is finding her.

He enlists the help of his friend, Agent Kendra Dean and her FBI-K9 partner, Annie. As soon as they are on the trail, they realize they're not simply searching for lost women-they are tracking a killer. They discover one body after another. Desperate to rescue Susan, Burke prays that the next body they find isn't hers.
