Greg Mortenson and David Oliver Relin, "Three Cups of Tea". Fascinating story of an ex (sort of failed) mountain climber, building schools in North Eastern Pakistan. Mortenson didn't summit K2, got lost returning to base camp, found his porter, got lost again, wandered into a tiny village, spent some time there to recover his health. Decided to repay the villagers by building a school because the village was too poor for a school building and could only share a teacher with another village, so the students walked long distances to study and on the days when they had no teacher, sat outside and tried to study by themselves. He went home, lived out of the back of his car (literally) and took about a year to raise the money. Fell in love at home, but she ditched him.
Of course much more happens ...
BUT.. he achieved his aims.
Good story, writing a bit melodramatic, but still a good read.
