Not many boys have to go in search of their missing father, but Billy Winter does. Billy steals aboard a cargo ship heading north to Alaska where his father was last seen. On the ship he is befriended by Sergeant Le Bulle, an off-duty Alaskan state trooper. In Alaska they set off on sleds pulled by huskies and meet Amka, an Inuit woman who is searching for her son who has also gone missing. The three decide to work together to solve the mystery of the missing men. But why is someone trying to kill them all? And why do Sergeant Le Bulle and Amka abandon Billy? Very few could survive alone in Alaska but Billy Winter must. This is his story.
