The Whisperers: Private Life in Stalin's Russia

very thorough and well documented. An unparalleled level of useful detail.
I got bored, though, eventually, because I did not get along well with how it is structured. I would have preferred chapters with general presentation (it was like this in this period, or it was like this in this thing) and then entire life stories per each person/family. As it actually is (a mix of history and bits of life stories continued elsewhere) it turns confusing and thick.
