Since we are on the topic of russian literature I'd definitely recommend reading something other than the usual suspects Dostoevsky and Tolstoy.
One of my personal favourites is Bulgakov'с Master and Margarita and The Bull's Hour by Ivan Efremov.
Bull's Hour is actually amazing as it explores societies built on different principles using a form of a novel.
>"Dostoevsky and Tolstoy"
I was born in USSR and was an still am avid reader. However never liked either of those two.
Totally agree about Efremov. Great writer
Some of the titles aren't translated - a cursory search did not turn up a downloadable version of the Bull's Hour, but search flibusta - titles are in russian but thanks to AI ...
