In the first book, Greg Mortenson worked to fulfill a promise he made to one community, and in doing so, he ended up building a succesful nonprofit: Central Asia Institute that works to bring education to the most remote areas in Pakistan and Afghanistan, especially for girls. Girl Power!
So here's this quiet and shy white man doing amazing things in this foreign country that he is forever linked to simply because he got lost on a climbing trip. Sometimes I get lost....and I just find my way home and dismiss everything on my way. I don't even pay attention to what is around me-I just focus on getting home. Greg got lost....and a whole new life was formed for him. His entire life is now formed around what is going on in random communities on the very far outskirts of countries half a world away from his home.
This book is the next chapter in Greg's life. It does a great job of describing some of the issues that make it difficult to turn monetary donations into something as simple as a 4-walled building that will become the only school in the region. It's not just that they need people to donate money. That's almost the simplest step to get the schools built.
