If you've missed them, the long arc of the Queen's Thief series features the three warring alt!Grecian kingdoms of Sounis, Eddis and Attolia getting their act together to avoid being absorbed by an alt!Babylonian empire. The books are heavy on well-researched worldbuilding, political complexity, and third-act twists; they are light on divine influence, though the gods do have a plan and they would rather like the protagonists to stop whining about it. Books include:
The Thief: A magus, his two apprentices, a soldier and a thief go on a life-changing field trip to steal a divine king-making relic, and Megan Whalen Turner shows off her unreliable first-person narration.
The Queen of Attolia: All three kingdoms start a slapfight with each other while the series protagonist sulks in his room, except when he's stealing important political figures from other kingdoms. Megan Whalen Turner would like you to know she can dance deftly around significant information just as easily in omniscient third as she can in first.
The King of Attolia: A sweet, honest guardsman punches his king in the face, and proceeds to regret every single one of his life choices. Megan Whalen Turner's like "look, this time I'm using limited third and telling you EXACTLY what my protagonist thinks and believes at any given time, it's not MY fault he only knows like 20% of what's actually going on."
A Conspiracy of Kings: The heir to the kingdom of Sounis is like "I COULD sort out this civil war by becoming king OR I could do hard labor for the rest of my life and honestly the latter sounds more appealing?" Megan Whalen Turner returns to first person but is too busy examining questions of ethics around violence in the political sphere to put all that much effort into setting up twists.
( This is the part that's spoilery for the first four books )
Anyway, yesterday I finally got to the point where I could read the just-published new book, Thick as Thieves. ( So this is the part that's spoilery for Thick as Thieves. )
