If you like short stories, Iād recommend The Complete Robot. I also like 1Q84 but this might be a different kind of sci-if than you have in mind.
The Expanse series is by far the best modern sci1fi out there. Murderbot Diaries is a very fun read Old Manās War is also great Armada is great if you love 80s/90s nostalgia and tropes Ghost Fleet and Burn-In are superb FICINT
Have you read Snow Crash and Seveneves? I love those and looking forward to reading more from Neal.
I liked the Gateway series by Frederik Pohl, especially the first 3 volumes.
If you can separate art from the artist and haven't already read them: Ender's Game & Ender's Shadow by Orson Scott Card.
Three Body Problem (technically called Remembrance of Earth's Past trilogy )
Dan Deadman series Carlucci series When Gravity Falls Walking Shadow Altered Carbon Gone World Dark Matter KOP Made to Kill series Automatic Detective Liquid Cool series Gun, With Occasional Music Mindspace series City Blues series Stainless Steel Rat Cyptonomicon Plutonium Blonde Bone Wires Pump Six Recursion
The Void Trilogy is a criminally underrated/unknown series. My all time favorite even as I continue to make my way through the "classics"
enjoying Kim Stanley Robinsonās Aurora right now. I have a lot of stuff to catch up on, so watching this
Some of my favorites: -The Foundation -Dune -Snowcrash -The Martian -Project Hail Mary Hard to pick between them, really can't go wrong with any of these!
recently finished Light Bringer so Red Rising series is top of mind for me. Gets so much better as the series progresses and Pierce Brown matured as a writer. If you venture in, keep in mind he wrote the first book in his early 20's...
All-Time: Blindsight by Peter Watts It's CC, hard-sci-fi (100+ pages of notes about the actual science in the back) and bleak as hell. So good. Recent favorite: There is No Anti-Memetics Division by qntm Uneven but incredibly inventive. Smarter than most sci-fi.
