If you can stomach it, Romeo Delaire’s “Shake Hands with the Devil” is a General's account of the genocide in Rwanda during the 90s (when Mad Albright would not say the word “genocide.").
For fiction - anything from David Gemmel, especially “The Rigante” series beginning with “Sword in the Storm.”
Also, Orwell's “1984” and “Animal Farm” are always worth your time.
I agree about “Fear No Evil.” It was an experience. And I’ve read the Orwell ones. The others sound very interesting too, thank you!
