I'm working through The Blue and the White. It's a story about a Russian Imperial Navy officer graduating just on the eve of WWI. It handles questions of ethnic relations (he's in love with a Jewish girl), social questions (his best friend from childhood becomes a socialist agitator), issues of culture, class, and society. So far it's quite good. Unfortunately I don't think it's been translated, but in my opinion Lavrenev is a fantastic author worth checking out.
