Last summer I spent several months reading an advance copy of this first volume of Stephen Kotkin's planned three book biography of the Soviet dictator Stalin. I would read a chapter then set the book aside for a while so I could mull over what I was learning. I also needed to rest my arms because this book weighs a lot! Stalin, who died in 1953, still casts a long shadow-he had an impact upon millions of souls. Those people that he ruled, that he terrorized, that he killed are nearly impossible to tabulate. My father's parents were among them.
