Alone in the vast white wilderness, Jessie learns that a young novice racer she met at the start of the race has been abducted. The girl's father is warned that no one but Jessie Arnold is to be told...or the girl will die. Speeding through the twists and turns of the icy, broken trails, Jessie has no time for fear. For somewhere in that lonely landscape, a killer waits for a chance to unleash his murderous rage on anyone who dares to get in his way.
