Three Cups of Tea by Greg Mortenson and David Oliver Relin is certainly a worthwhile read....not the best book I've read this summer, but it certainly stretches your thinking. The back of the book gives a great summary....."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. Over the next decade Mortenson built not just one but fifty-five schools---especially for girls---in the forbidding terrain that gave birth to the Taliban. His story is at once a riveting adventure and a testament to the power of the humanitarian spirit."
I especially found this book interesting since I spent two months in Pakistan doing an Occupational Therapy internship (that's a WHOLE 'nother post...perhaps when I am back in the US and have access to my scrapbooks....). I visited many of the places he talks about in the book. His is an amazing story of how one person really can make a difference in the world.
