An interesting mystery, set in a fascinating time & place, filled with colorful characters who discuss religion, politics, & the clash of empires as they go about their daily lives. I love Li Du, the MC, and Hamza, his side kick (in fact, I'd love a series in which Hamza was the MC); I love the descriptive writing. And I loved that it was snowing in my town as I finished this book set during a snow storm high in the mountains of Tibet!
