Query: Excellent perspective on how Afganistan came to be in crisis

I love this book. It is clear-headed and honest, with a quirky sense of humor. You feel as if the author is an old friend. He definitely is a rock and roll American with an Afgan soul. His experiences of living in Afganistan as a child and his later trip back to the Islamic world is both enlightening and completely engrossing.
