Book 25: The Mimicking of Known Successes. A mystery/cop procedural novel, sort of, which takes place on a gas giant planet that has been loosely colonized. There's a lot of world building and a cop+scholar who must combine forces to figure out how a person disappeared from a transportation platform at the end of the world. But they have some history which also needs to maybe be resolved. I had a hard time visualizing some of this but I really enjoyed the story.
