Also anything by Adrian Tchaikovsky. The one that stood out from him was the Void series and Alien Clay. Of course I'd you haven't read him do start with his main series as it was excellent too, but I'm pretty sure before 2020
Assuming you're talking Children of Whatever, eh, I'm not sure I agree. IMO some of his other novels are _far_ better (Children of Whatever are _good_, but some of the other stuff is _great_.)
Elder Race and Dogs of War are also awesome entry points for people who enjoy S&S fantasy and military themes, respectively.
Also, "There is no anti-memetics division" is interesting but I'm divided about it. The first 60-70% is great, but after that it's kinda "meh" and by the time I finished the book I was glad it was over lol. The initial 2/3rds of the book are really good and almost makes up for the lackluster ending (imo).
