Speculative/surreal/philosophical science fiction?
Im looking for book recommendations. I love sci fi and specifically love BIG CONCEPT sci-fi that really makes you ponder and challenges your perspective. I love dream state concepts, weird and surreal, that kind of thing. I also like hard sci fi, but generally only when its well written and ties in all kind of allegory and symbolism. Also open to weird and surreal fiction with philosophical themes that aren't strictly sci-fi. Some of my favorites:
Adrian Tchaicovsky - literally anything he has written, but especially his stand alone works like Shroud, Alien Clay, Cage of Souls, Service Model
Ursula k. Le Guin - all of it
Kurt Vonnegut - everything, but especially Sirens of Titan, maybe my all time favorite book
Philip K Dick - all of it, but Ubik is a favorite
Murakami - everything
China Mieville - Embassytown, Kraken
Joanna Clarke - Piranesi
There are more, but those are the handful that come to mind.
