I just finished reading Life and Death in Shanghai by Nien Cheng. It was a wonderful, albeit sad, book about the Cultural Revolution in China in the late 60's and early 70's. The author was wrongfully imprisoned for 6 1/2 years and she gives an account of China during that time which is very eye-opening.
Currently I am reading Lincoln by David Herbert Donald. I love American history. So far, so good. I think one of my favorite books has been 1776 by David McCullough. I also really liked his John Adams as well.
