Not enough people have heard of and read The Quantum Magician so I will continue to recommend it. It’s quite the wild ride.
For starters, definitely read Termination Shock by Neal Stephenson. So good.
And The Peripheral by William Gibson, although I wasn’t a huge fan of the follow-up novel called Agency.
Also, A Memory Called Empire and A Desolation Called Peace by Arkady Martine should be on your to-read pile if you liked The Expanse, I think.
Oh yeah, and so far I think my favorite book of 2023 has been Cory Doctorow’s Red Team Blues. It’s a super fast read and a lot of fun if you’re at all into computer security. Very unlikely hero too—a retirement age forensic accountant living out of a rock star bus, traveling the US in search of good wine and good food, haha.
K. B. Wagers is a great author. I started with Behind the Throne and read the whole Indranan War series. Next trilogy was the Farian War. Haven’t read past those although I want to! Her new stuff looks interesting.
I also really like N. K. Jemisin. My favorite is the Dreamblood series.
Another vote for NK Jemison, she’s good.
I find Mieville’s books dreamy in a way (though gritty there is a dreamlike or trippy quality to them) so will also suggest:
Ian McDonald Charlie Jane Anders Patricia McKillip if you like fantasy The book “This is the way you lose the time war”
I’ve been enjoying Django Wexler’s Shadow Campaigns series so much. If you like these sideways military stories, Naomi Novik has a good one too.
If you like Neal Stevenson, will probably like William Gibson too, they are different but I like both.
Martha Wells’ Murderbot series, starts with All Systems Red
Anne Leckie’s Ancillary Justice series
Ninefox Gambit by Yoon Ha Lee
Tamsyn Muir’s Gideon The Ninth (lesbian necromancers in spaaaace!)
JB’s The Cruel Stars
And file under older but still great:
Jon Courtney-Grimwood’s Arabesk series, cyberpunk alt history set in Alexandria, starting with Pashazde
The Laundry Files by Charles Stross (actually spy / horror) starting with The Atrocity Archives A short story, Down On The Farm, set in the same universe is free to read here
I recently read the Bobiverse books, and those were quite fun.
Daniel Suarez is another good one (start with Daemon), as is Ian McDonald (Dervish House, the Luna series).
