Into the Wil (1996) by Jon Krakauer is a bestselling non-fiction book about the adventures of Christopher McCandless. It is an expansion of Krakauer's 9,000-word article, "Death of an Innocent", which appeared in the January 1993 issue of Outside. Krakauer intersperses McCandless's story with a discussion of the wilderness experiences of people such as John Muir and John Menlove Edwards, as well as some of his own adventures. Krakauer first went to Alaska in 1974 and has returned there twenty times since. He spent three years carrying out the background research work for this biography.
