There is a series of books by a man calle Gary Paulsen which are the best i've ever read. Theys are called Hatchet, Hatchet the return, Hatchet the winter and Hatchet the call. There are about a boy called brian who crashes in a plane in the canadian wilderness and who has to survive and learn skills of bushcraft. I thought the best one was Hatchet the winter. They are aimed at children and because i'm 14 i enjoyed it but there's no reason why adults can't aswell. Great books, read them!
