I haven’t had any luck in finding sci-fi books recently. I’m looking for a longer story that takes its time to establish the world/universe and the characters living in it. I like the idea of exploring space or futuristic cities/landscapes and being on a journey together with the protagonist. The story doesn’t have to have a happy end or flawless characters, but I also don’t like it when everything is hopeless/dystopic and all the characters stumble from one flawed decision to the next one. Some examples of what I enjoyed so far are:
- Dune
- Project Hail Mary
- The Expanse Series
- Hyperion Cantos Series
- Bobiverse Series
- The Murderbot Diaries Series
- Tuf Voyaging
- Night’s Dawn Series (Might not be for everyone… contains excessive violence and some smut, but also some very interesting ideas)
- Vatta’s War Series (I usually don’t like military sci-fi, but this one wasn’t bad)
- The Interdependency Series
- Falling Free
If you enjoyed some of these stories and have any similar suggestions, feel free to share them here. If not, maybe consider checking out the list above… I highly recommend each of these entries.
You’ve already had a recommondation for most of what I would suggest to you, but I will happily second the suggestions for the Revelation Space series by Alastair Reynolds, the Teixcalaan series by Arkady Martine, and the Imperial Raadch/Ancillary series by Ann Leckie. All have excellent worldbuilding and tell stories that depend heavily upon how their characters interface with the worlds they inhabit.
A little pulpier in tone, but still very well put together, I’d suggest as well the Wayfarers series by Becky Chambers, and especially the Locked Tomb series by Tamsyn Muir. The latter is a bit more fantastic space opera as opposed to some of the harder sci-fi you’ve mentioned, but Muir knows how to write a setting that is absolutely dripping in gothic horror, and still take you on an emotional roller coaster fully of highs, lows, and humor as you read it. It seems to be a bit of a love-it-or-hate-it series from the other conversations I’ve had about it, but I love it and I’d be remiss not to suggest it.
I’d also suggest, if you’re not averse, dipping your toe into the fantasy genre as well. There’s a broad range of authors there who have done excellent work building fantasy worlds that are structurally deep and compelling, and have many science-fictional qualities. Along these lines I’d suggest Robert Jackson Bennett’s Founders trilogy, or N. K. Jemison’s Broken Earth trilogy – though, fair warning, both of these broke me in the end emotionally. Worth it, though!
