Looking for something new to read after The Expanse

Any fiction suggestions for a somewhat picky reader? The Expanse lasted me a long while but I'm finishing up the novellas now and need to start looking for something new. Not necessarily in the same genre.

I don't have a lot of books under my belt as an adult, but some of my favorites have been Stoner by John Williams, Shantaram by Gregory David Roberts, East of Eden, Catch 22, Flowers for Algernon, and Harry Potter. Kind of all over the place I guess. 😅

I've also enjoyed John Williams' other novels, Piranesi, The Things They Carried, House of Leaves, and Ender's Game and the sequel.

Some books I didn't really care for include Hitchhiker's Guide (although I loved the first half), Lolita, Sharp Objects, Turtles All the Way Down, The Stand, The Road, 1984, and Fahrenheit 451.

I'm always overwhelmed trying to find something new, so thanks for any suggestions!

EDIT: Thank you all! It'll be a bit daunting exploring all these new books but not nearly as daunting as if I had no guidance, so I really appreciate it!
