Jonny Reads Davy

Davy, a sci-fi novel by Edgar Pangborn, now out of print.
It's ironic: I last read this book when I was around fourteen. The main character was a man writing his own biography in a post-apocalyptic Northeast USA, starting when he was fourteen. Now I am about the age of the narrator when he was ostensibly writing the book.
It's been a long time since I just sat and read out in the woods, but a person needs to unwind from time to time, and I can't think of a less artificial place.
