Like the title! I've been getting back into reading for pleasure, and want to know what you like! I recently read Piranesi and loved it. I've heard good things about The Poppy War and Babel by R.F. Kuang, has anyone read them?
Generally just want a bunch of recommendations from your favorites, on our commie corner of the internet. No genre needed! 
1984 ofc
Roadside picnic and The Road are definitely at the top. I am legend is so much better than the will smith movie genuinely brilliant story. His dark materials is a great series worth reading.
If you've ever seen the red dwarf TV series I'd recommend the books as they have a much darker more serious vibe but also hit a lot of the same comedy notes as the show. It also has a more satisfying storyline and payoff.
Once in those early years he’d wakened in a barren wood and lay listening to flocks of migratory birds overhead in that bitter dark. Their half muted crankings miles above where they circled the earth as senselessly as insects trooping the rim of a bowl. He wished them godspeed till they were gone. He never heard them again.
Oh, will add those, thanks! Roadside Picnic is fantastic, I agree, I really loved it.
If you have a few hours try the STALKER movie, a loose adaptation of Roadside Picnic. It's one of the best movies.
The main positive is that the movie is just one of those "trailing end of the zombie fad, what IP can we latch onto" types and has basically nothing in common, so it doesn't spoil the impact of the book.
