If you like travel or travel books, and are even remotely curious about Afghanistan, this is the book for you.
Rory Stewart, the 'first tourist' to enter the country right after the Allied offensive in 2001, writes simple but compelling prose. Foolhardy yet inspiring, this book was a very easy read for me.
Try a few pages, I don't think you will be disappointed at all.
