I was very disappointed with this book. The substance was thin at best. It was not what I was expecting. I thought there would be more detail on Mao's life. A more pronounced understanding of the man and what drove him. What was presented appeared to be no more than speculation. I really don't think that Mao's preoccupation with his bowel movements is overly relative, yet the author felt this was important enough to mention more than once. Just a very inept presentation of the story of a man with significant impact on world history. I expected a lot better.
