Less than 48 hours after twelve-year-old Chris casts off on a trip to sail down the Alaskan coast with his uncle, their boat sinks. The only survivors are Chris and a boy named Frank, who hates Chris immediately. Chris and Frank have no radio, no flares, no food. Suddenly, they've got to find a way to forage, fish and scavenge supplies from the shore. Chris likes the company of a curious friendly raven more than he likes the prickly Frank. But the boys have to get along if they want to survive.
