The Rape of Nanking
It's amazingly horrible what human beings can do to each other. In 1937, Japan invaded China, reached the capitol, Nanking, and proceeded to humiliate, torture, rape, and execute thousands of Chinese soldiers and civilians over the course of 6 weeks. Brutal.
And Another Thing
The 6th book in Douglas Adams's Hitchhiker's Guide to the Galaxy trilogy. It wasn't bad, but it could've been better.
