Three Cups of Tea by Greg Mortenson & David Relin

After a failed attempt to climb K2, Mortenson was nursed back to health in a northern Pakistan village. To repay their kindness, Mortenson vowed to build the village a school. That experience began a continuing journey of building schools for the marginalized people of Pakistan. Gracing bestseller lists for years, this is an inspiring book. While not a Christian ministry, the work Mortenson does is a great example of what one person can do to change the world. This would be a good book for your reading group too.
