Incident at Hawk's Hill by Allan W. Eckert (1991, Paperback, Reissue)

This is one of the most interesting stories I've ever read. I first read this in high school because the cover looked interesting, and I've never forgotten this book. So much so that 10 years later I am buying it because I want to read it again and again. It is based on a real story of a young boy with communication difficulties (possibly autism) who gets lost in the wild and is taken in by a badger who raises him as her "pup." It is a story that will stick with you forever.
