Have some plot - need title
A number of native american teenagers (3 to 10) in the pacific northwest (maybe Washington state or british columbia) have been sentenced to spend one year in jail by a white sheriff. Some elders of the local native american tribe offer to substitute punishment according to their tribal culture. This punishment consists of being banished to an island for one year. They are far enough away from mainland that it is not easy to get off. They must learn cooperation and survival.
