morolf: I'm half through Stephen Kotkin, Stalin 1878-1928, Paradoxes of power.
First volume of a planned Stalin trilogy. Too long (about 800 pages text, plus many detailed endnotes) and a bit tedious. So far it's more of a general history of Russia and of Bolshevism in the early 20th century. I'm not entirely convinced of the concept, though parts of it are quite interesting.
I read Hitler and Stalin Parallel Lives. Followed both leaders from their childhoods all the way through to the end. Yeah, Stalin was a primo jerkoff. Hitler too, but Stalin tends to get a pass from the left. Both had crappy tastes and they both nearly ruined facial hair for about 50 years.
