Query: This is a Must Read!

A friend spoke of this book and peaked my curiosity. I purchased it for myself and also as Christmas gifts for my adult children. We have each said the same thing- we couldn't put it down after we started reading it AND that everyone needs to read it. Greg Mortenson is truly an amazing person. All I can say is- God bless him, those working with him, and the work they do. I now intend to purchase his next book and can't wait to read about his new adventures. The world would definitely be a better place if there were more people like him.
