This is one of my all-time favorite books!! I have read it at least 3 times in the past few years - I love true stories that read like novels, and introduce me to people I come to care about as if they are family!
"In 1993 a mountaineer named Greg Mortenson drifted into an impoverished Pakistan village in the Karakoram mountains after a failed attempt to climb K2. Moved by the inhabitants' kindness, he promised to return and build a school. Three Cups of Tea is the story of that promise and its extraordinary outcome"....
....and here's the best part! Because it was printed in 2006, good used copies are available for $3.98 (with free shipping) at Better World Books http://www.betterworldbooks.com/three-cups-of-tea-one-man-s-mission-to-promote-peace-one-school-at-a-time-id-9780143038252.aspx
or you can find a copy at most libraries, read it and then decide if you would like your own copy to keep and share.
