4.0

This travelogue/memoir is perfect for anyone who enjoys wild, wide open spaces, exploring new cultures, cycling, environmental conservation, science, geopolitical history, finding one's way in the World and/or space travel to Mars.

I know. There's a lot going on in this book, but Harris manages to thread these varied topics together in a well-written and introspective journey along the historic Silk Road.

Definitely worth a read!
