"Yale University’s Timothy Snyder discusses the mass murders committed by the Nazi and Stalinist regimes, and looks at how both the German and the Soviet killing sites fell behind the iron curtain after World War II, leaving the history of mass killings there in darkness. In Bloodlands: Europe Between Hitler and Stalin, he looks at what happened under totalitarianism, when Stalin killed millions of his own citizens and Hitler murdered six million Jews, as well as nearly as many other Europeans."

This is the best book I’ve read on WWII in years, from a reading habit of nearly 100 books. It’s a side of the war only glimpse.
