A similar theme to Adrian Tchaikocsky's most recent standalone work "Alien Clay". I saw on a podcast that he said that in Alien Clay, he started from the reasoning 'What if life developed not with competitive natural selection, but in a maximally cooperative fashion, where every organism is capable of cooperation with any other corporation of organisms', and here is another variant of that theme - or perhaps its opposite, 'What if life was entirely one species'. Very nice.

Also he does love his evil, totalitarian states. Here it's the Concern. In Alien Clay it's the Mandate. I think his name for the philosophy in his Tyrant Philosophers series is very clever: Perfection. The fascist ersatz-Imperial-Britain-copies pursue a doctrine they call Perfection - which is obviously what every monomaniacal totalitarian pursues, the word they'd give to their philosophy is always best translated as Perfection.
