I'm almost finished listening to this book. I'm really surprised by how much I am enjoying it. Moon's innocence about the "real" world and his expertise about living off the land are a great juxtaposition. He is surprisingly sociable for a child who grew up in such an isolated manner.
I admittedly know little about living in the wild; however, the author’s descriptions of what Moon does to survive ring true to me.
