Into Thin Air by Jon Krakauer

Krakauer examines what it is about Everest that has compelled so many people -- including himself -- to throw caution to the wind, ignore the concerns of loved ones, and willingly subject themselves to such risk, hardship, and expense. Written with emotional clarity and supported by his unimpeachable reporting, Krakauer's eyewitness account of what happened on the roof of the world is a singular achievement.
