Another from NPR's Backseat Book Club list. I was reading through What's that Book on reddit and someone posted about a book where a kid lives in the forest in a burned out tree. Another poster identified the book as My Side of the Mountain. That description made me want to finally read the book.
I ended up really enjoying it. It's like all the best parts of Hatchet without the divorce story line and repetitive writing. I am (as I have said before) very into these books where kids live off the land on their own.
