I've read four of the Murderbot series, slight but enjoyable. I re-read Peter Watt's Blindsight, followed by Echopraxia. They're both intriguing, but the second isn't as meaty as the first. His exploration of ideas is great, though. From one end of the positivity spectrum to the other, I'm close to finishing Kim Stanley Robinson's Ministry of the Future.
The first half shows how much naughty word we're in, which he depicts incredibly well, and the various ways of overcoming and reducing the forces of climate change are absorbing and informative. It's actually possible, even from here and now. He mentions them in passing but Kim's really too nice to write the bits I'd like to have followed: eco-terrorists and black departments that did the dirty work. Especially after seeing how the book starts. That's gonna stick with me - KSR should try his hand at horror.
