This thread seems more alive than the main reading one, so even though I'm not tracking my books read, one I read this year and loved is Cahokia Jazz by Francis Spufford. It's a detective noir set in an alternate 1920s where indigenous people revived Cahokia (an ancient city across the river from modern St. Louis), so there's a U.S. state that's majority indigenous, with large white and black populations as well. With Jim Crow in nearby states and the KKK on the rise, the main character, an indigenous man raised in another state, has to investigate a murder that threatens to blow up the city's balance of power. Lots of cool characters, rich worldbuilding, a good central mystery, and jazz.
