Children of Time: What if spiders were sapient?
Children of Ruin: What if octopi were sapient?
Children of Ruin (again): What if slime mould were sapient?
Children of Memory: What if raven couples were sapient?
The Final Architecture: What if moons were sapient?
Dogs of War: What if networks of sapients were sapient?
Bear Head: What if Trump were sapient?
He’s a favourite of mine as well. Have you read Cage of Souls? It breaks your sapience mold, and of his books I liked it best until he wrote The Final Architecture trilogy.
It’s almost fantasy-like in plot, but the world is shown through a lens of “lost technology” rather than “magic”.
I haven’t. It’s not for sale as an ebook in the US, sadly.
I’m working my way through City of Last Chances right now and am really enjoying it. It’s straight fantasy.
