Three Cups of Tea by Greg Mortenson

 "One day in 1993, high up in the world's most inhospitable mountains, Greg Mortenson wandered lost and alone, broken in body and spirit, after a failed attempt to climb K2, the world's deadliest peak. When the people of an impoverished village in Pakistan's Karakoram Himalaya took him in and nursed him back to health, Mortenson made in impulsive promise: He would return one day and build them a school. Although he was homeless "climbing bum" living out of his aging Buick in Berkeley, California, Mortenson sold what few possessions he had to launch one of the most remarkable humanitarian campaigns of our time."
