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:
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.
Not sure if it tickles your fancy, but if you're in the mood for a humorous space adventure with an elaborate story and serious undertones, give Ben Yahtzee Croshaw's Will Save The Galaxy For Food a try.
Also, I haven't seen Adrift and the Outer Earth Trilogy by Rob Boffard being mentioned here. Especially the former managed to instill a sense of dread in me while the story unfolded. The latter is a rather long read, though the first book (Tracer) is self-contained.
ETA: a somewhat different style, but if you like futuristic worlds / galaxies with tons of intricate details, try The Long Way to a Small, Angry Planet by Becky Chambers. Her world (universe, in fact) is incredibly rich in detail and diversity. Each alien race she introduces has its own complex backstory, values, language and culture.
The other books in the series didn't grip me like this one - they add a lot of background, and in that she's a genius, but for my taste the story was somewhat lacking.
Ditto on the Becky Chambers series. I actually liked the second book the most narratively, and if the OP likes Murderbot, they may really enjoy similar themes around artificial intelligence. I also really liked the final installment. It's a familiar setup with strangers locked in a room together, but I found it very meditative. Also, it wraps up one series character's journey to a decision that I found very profound.
I'll add "Will Save The Galaxy For Food" to my list, thanks! I've actually read Angry Planet a while ago and enjoyed it. A story that is really cozy and easy to read, that helped me through difficult times. In case you haven't read the Murderbot Diaries, I'd highly recommend those. Despite the name, it's also very nice to read.
