Don't know what you are looking for here are some things that I have quite liked:

1. Perdido Street Station: It is set in a steampunk dark fantasy universe and the setting is very well realised, also the author is a lefty.
2. The unbearable lightness of being: The prose is pretty good. It is written as the musings of the author told via some story he is cooking up in his head. It has a critical perspective towards the Soviet Union and Communism so might rustle your jimmies if you are very pro :tank:
3. Lolita: Is an uncomfortable read at times but it got me convinced I was reading the thoughts of a narcissistic European pedo. Also 10/10 prose.
4. Who do you think you are?: Strongly recommend. It is about a working class girl from a village in Ontario. The way she writes about things from a distance without judgement but still very personal is quite amazing.
5. The Bell Jar: Very good and very depressing.

EDIT: Oh I should say literally anything by Wodehouse. Every sentence is sublime joy.
