Into the Wild by Jon Krakauer
In April 1992, a young man from a well-to-do family hitchhiked to Alaska and walked alone into the wilderness north of Mt. McKinley. He had given $25,000 in savings to a charity, abandoned his car and most of his possessions, burned all the cash in his wallet and invented a life for himself. This is the haunting story of 22-year-old Chris McCandless, who walked into the Alaskan wilderness in the spring of 1992 and whose body–along with a camera with five rolls of film, an SOS note, and a cryptic diary written in the back pages of a book about edible plants–was found six months later by a hunter.
