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. His name was Christopher Johnson McCandless. He had given $25,000 in savings to charity, abandoned his car and most of his possessions, burned all the cash in his wallet, and invented a new life for himself. Four months later, his decomposed body was found by a moose hunter. Jon Krakauer constructs a clarifying prism through which he reassembles the disquieting facts of McCandless's short life. Digging deeply, he takes an inherently compelling mystery and unravels the larger riddles it holds: the profound pull of the American wilderness on our imagination; the allure of high-risk activities to young men of a certain cast of mind; the complex, charged bond between fathers and sons
