Boxers & Saints by Gene Luen Yang (2013)
Before I heard about these books, I hadn't even heard of the Boxer Rebellion. Reading Boxers first, I think I got the basic idea of what it was about. When I began reading the parts about the men turning into ancient gods, I ended up reading the Wikipedia entry about the Boxer Rebellion because I couldn't trust this book as fact. Turns out, the Boxers actually did believe that spirit possession helped them to fight better. I really enjoyed Little Bao's story and the vibrant art.
I looked forward to reading these as I enjoyed Yang's American Born Chinese so much, but only Boxers lived up to my expectations. Although collectively far from perfect, they tackle an interesting and overlooked historical topic and would be great for discussion.
