EVE Fiction

Gonna have to second Iain M. Banks' Culture novels.

They are set in various times and places; they involve various elements of the Culture, an advanced civilization who is most notable for considering their AI's to have equal rights to biological life. The most advanced AI's are called 'Minds' and generally inhabit and control badass spaceships. Smaller drones have AI's sufficient for the culture to consider them sentient, rights-holding entities as well. Many parts of the books are told from the POV of Minds and drones.

Although the Culture is anarchistic and leaderless, much of the decision making happens when a group of Minds analyze a situation and decide what, if anything, they should do. The Culture is post-scarcity; the manufacturing capabilities and resources available are such that everyone can have whatever they want for free. Thus money isn't used within the Culture.

Many Culture citizens change their sex occasionally, just by thinking about it. Most Culture 'pan-humans' are also born with a set of drug glands that can secrete any of hundreds of various side-effect-free drugs just by thinking about it. Some (especially the operatives for Special Circumstances) have a 'Neural Lace,' a brain implant that improves their thinking speed and interfaces with other machines, transhumanism style.

The books are not sequential so you can read them in any order. My suggested reading order, if you want to take advantage of the few characters and tropes that occur in multiple books, is:

Matter - A Culture operative interferes to save a developing world

Consider Phlebas - follows a soldier in the Idiran War, the only full scale war the Culture has fought

Look To Windward - Another civilization plots a terrorist attack on the Culture; lots of followups on the Idiran War

The Player of Games - A game player attemps to beat another civilization at their own game to prove the Culture is better

Excession - A time-space anomaly beyond known Culture technology causes havoc as various groups fight to seize it

The State Of The Art - A collection of short stories, including one where Culture operative Diziet Sma goes to Earth

Use of Weapons - A Culture mercenary with a sketchy past kills lots of people

Surface Detail - Some civs transcribe their bad people's minds into virtual reality 'Hells' to punish then beyond death. A war is fought to keep or eradicate these hells

The Hydrogen Sonata - A civilization prepares to 'Sublime' (i.e. everyone vanishes into some higher plane) while others attempt to prevent the sublimation from taking place

Inversions - Two operatives act as advisors in medieval civilizations (barely a Culture novel IMO, not much tech or other Culture tropes)

My favorite book is probably Matter. It's hard to choose, I loved them all except Inversions.
