What is the book Dogsong by Gary Paulsen about?

You will have to read it o see. And remember don't judge a book by its cover! I did that to his book Hatchet but my brothers told me to read it so I did now its my favorite book! If I knew what the story wee about id say but it should be the best! Anything by Gary Paulsen is the greatest he always is going deep into thought!
