This is a cooperatively written, serialized prequel to the "fantasy-of-manners" Swordspoint (which in turn is followed by the heavily recommended The Privilege of the Sword). I haven't read the background but it feels like it was handed around between authors with a rough outline of where they wanted to end up, and everyone seemed to be on the same page when it comes to the spirit of the work. It's mostly solid storytelling and really has the feel of a 19th century serialization. Occasionally this doesn't work--a few chapters felt like they'd be heavily abridged in most editions, as characters seemed stuck in bland dialogue and parties while waiting for the story to pick up.
It is a pretty good story when it is going full steam. The Riverside setting is a late medieval or early renaissance world, fantasy in the sense of being ahistorical instead of magic heavy. The depiction three different cultures--the local nobles, the Riverside lower class, and a group of foreign traders--is done skillfully and the interactions feel quite natural.
The main selling point Duchess Tremontaine, much young than her appearance in Swordspoint. She's a vain, evil, manipulative and a genius, much in the mold of Francis Underwood in House of Cards. She has a few rivals with the wit to stay in the game, most notable the Balam "trader" Kaab, a young foreign merchant trained in the subterfuge-and-spying part of the family business. A young genius mathematician, kind and vulnerable and somewhere "on the spectrum" while she's working on Copernican solutions to astronomy, is a brilliant addition to the cast too.
