Edge of nowhere - John Smelcer

This is an astonishing
tale of survival; a poignant Robinson Crusoe story, based on true events. When Seth and his dog, Tucker, are washed overboard from his father's fishing boat during a torrential storm, they are assumed drowned. But by good fortune, Seth and Tucker make it safely to one of the hundreds of islands that line the Alaskan coast. Over many months, the boy and his dog make their way, island by island, towards home, while Seth's desperate father never gives up hope. Along the way, Seth learns many hard lessons about survival, and even harder lessons about himself.
