Others may have mentioned it (happy to see Terry Pratchett getting a lot of love), but would definitely recommend anything by Vonnegut! Love his writing style and his approaches to humor and world building. Slaughterhouse Five is a great one, as is Sirens of Titan.
Also, not certain how well they hold up, but I really enjoyed the Redwall series back in the day! I was much younger at the time, though.
That’s just turning it off with Style✨
