With her cabin a pile of ashes and her lite in pieces, champion Alaskan "musher" Jessie Arnold has gratefully accepted a friend's proposal that she drive his motor home up from Idaho, along the Alaska Highway — a breathtaking, two thousand-mile-long route winding past hot springs, glaciers, and ice-blue lakes. But the idyllic trip takes a dark turn when a teenage hitchhiker brings terror aboard. Frightened and alone, Patrick Cutler disappears just before the police inform Jessie that the young runaway is wanted in connection with two shocking murders. Suddenly she is cast into a raging maelstrom of dark secrets and deadly consequences. And the cold and empty road she's traveling could be leading her not to her home...but to a grave in the trackless wilderness.
