I just finished the tome that is "The House of Government" - a look at the founding, arrangement, and domestic habits of/in the Soviet House of Government across from the Kremlin. It's a really fascinating look into Bolshevik psychology/culture at the highest level and shows how it really was practically an atheistic religion at that level. So much of the framing is centered around what books people are reading, how they are living (and indulging in the petty comforts of "bourgeois domesticity"), and so on. It has some sections that are a bit of a slog, going into boring details of domestic routine, but needless to say it picks up as it progresses into the late 1930s...
