I second the recommendation, I read that a few years ago and it is an incredible story. Krakauer tells it as one who was gripped by Everest fever, fascinated by the mountain itself but also the colourful personalities drawn to the most serious level of high altitude mountaineering-- but also a man who has seen his friends succumb to the madness of obsession, and ultimately death. It was hard for me to put down; a compelling read for anyone interested in travel or the outdoors.
