Three Cups of Tea by Greg Mortenson & David Oliver Relin

Second Hand 

'Here we drink three cups of tea to do business; the first you are a stranger, the second you become a friend, and the third, you join our family, and for our family we are prepared to do anything even die.

Haji Ali, Korphe Village Chief, Karakoram mountains, Pakistan

In 1993, after a terrifying and disastrous attempt to climb K2, a mountaineer called Greg Mortenson drifted, cold and dehydrated, into an impoverished Pakistan village in the Karakoram Mountains. 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. Over the next decade Mortenson built not just one but fifty-five schools especially for girls in remote villages across the forbidding and breathtaking landscape of Pakistan and Afghanistan, just as the Taliban rose to power. His story is at once a riveting adventure and a testament to the power of the humanitarian spirit.
