Looking to get some intellectual diversity—what books stuck with you?

Hi friends! I’m reading a book a week this year, and I’ve found myself falling into a bit of a trap where the only things I’ve been reading lately is queer sci fi (go read Ancillary Justice) or Romantasy (I know). I enjoy both genres much like one would enjoy watching a Transformers movie, but I should probably broaden my taste a little. I need to detox from action-movie books.

Would you be able to recommend a fiction book that compelled and challenged you, maybe one that made you think about it for weeks afterwards? Ideally I would prefer the book is 500 pages or less but recommend whatever you want :) I am worried about finding some books dry after reading so many easy-pleasure novels, but I’ll challenge myself!

Edit: all of these recs are great, thank you! I will work my way through a ton of these. I appreciate all of you!
