I had dim memories of this book from grade school, and the outdoor theme brought me back to it. The premise is simple: a boy runs away from his home in New York city to survive in the wilderness, and succeeds.
I wasn’t disappointed. This is one of those books written for kids that has plenty of insight for adults too, which is probably what keeps it around. It is getting dated, but in a good way, marking the way our cultural perception of wilderness is changing.
