Independent Katie Lachlan has caught the eye and heart of a rich suitor who won’t take no for an answer. Luke Savage killed a man in a gunfight and swears he’ll never carry a handgun again. A strong attraction and mutual dependence link them together for a journey along the brand new transcontinental railroad, as she flees the suitor who stalks her and he runs away from his past. Instead of safety, they find new danger as they are forced to travel on foot across a wintry landscape. While Katie learns that independence is no match for force, Luke discovers that saving Katie is more important to him than the vow he made. Striving together against wilderness, gunfighters bent on retribution, and a frontier town on the brink of riot, they find their strength, their convictions, and their very love tested by adversity and danger.
