What books would you recommend for me?

I used to read voraciously in my youth, but as an adult it is very difficult to get into a story, even if it seems to be good. So, I'm asking for what you'd recommend... based on a few options.

I typically love/hate dystopian options that show that humanity is just a complete horrorshow. That being said, I haven't been able to get past page three (I think it was?) in Clockwork Orange. But, some of my favorite books are: The Lord of the Flies, 1984, To Kill a Mockingbird, and Tale of Two Cities in backwards order (that is, Dickens' is my favorite, and Lord of the Flies is still great but the least of those four).

I feel that futility and the rest of the world hating on you or just being its normal awful self are the main themes I seem to gravitate to.

As I mentioned though, I still intend to read Clockwork Orange but I'm not a fan [yet?]. I also read The Good Earth when I was about 11, and honestly, it's a godawful book but I read the whole thing because its horror kept me reading. Just putting that out there for ideas. Also I'm not much of a fan of sci-fi, unrealistic fantasy (though that might be an exception), or zombies/apocalypse.

So with all that in mind, does anyone have anything either modern or classic that you'd recommend?

EDIT: THANK YOU ALL! (And feel free to continue adding more suggestions!) I just wanted to say thank you for so many potential options; I just have to get over to the library for a card (scheduled for Friday), and what I can't get there or something that seems a little too dense, I will look into audiobook options since I drive a lot.
