He has a two-book set coming out in September! Boxers and Saints, about the Boxer Rebellion in China. Looks stunning!
From the publisher:
The Boxer Rebellion is a war that took place on Chinese soil over 100 years ago. Back then, the Chinese government was incredibly weak. Western powers were able to establish concessions – pieces of land that functioned as colonies – all across China. The poor, hungry, illiterate teenagers living in the Chinese countryside felt embarrassed by their nation’s weakness, so they came up with this ritual that they believed would give them mystical powers. Armed with these powers, they marched across their homeland into the major cities, killing European missionaries, merchants, soldiers, and Chinese Christians. Because their martial arts reminded the Europeans of boxing, they became known as the Boxers.
