Query: Mao, the Unknown Story

This book is a "must read" for anyone who cares to learn what kind of people are the communists, how they don't value human lives, unless it's their own. The cruelty and devil-like mentality is extraordinary. Documented proof of Mao's mass murders for the sake of his personal power. Also, by reading this book, you learn tons of small facts about Chinese customs and people, which is fascinating. Strongly recommend for any intelligent thinker!
