I just finished Normal People, which was my first Sally Rooney book. I loved it, but I wouldn't say it had a lot of political theory, just light commentary by the characters. I take it you recommend Beautiful World?
I'm currently reading The Bricks That Built the Houses by Kae Tempest. It might be a good candidate, but I'm not far enough through to really recommend it yet.
Some that come to mind:
- Han Kang - We Do Not Part or Human Acts
- Michael Ondaatje - In the Skin of a Lion or Anil's Ghost
- James Baldwin - Another Country
