Child 44 is about as far as my Russian reading goes and its not too taxing to be honest.
Actual history books or novels and Memoirs like the ones i've listed above?
If you mean novels and memoirs then the following are good, although some of them can be hard to find
Serge- Memoirs of a Revolutionary
Platonov- Happy Moscow
Platonov- The Foundation Pit
Lyons- Assignment in Utopia
Kravchenko- I chose freedom: the personal and political life of a Soviet official
If you mean actual history books is there any subject in-particular you're interested in e.g. the Terror, Collectivisation, Stalin, the Space Race?
