Not a particularly long novella, but Arkady Martine pulls off jamming several genres in there. The story seems like a murder mystery at first, with the setting being a cyberpunk-esque dystopian future in a nowhere town in California desert. There are shady conspiracies. There are creepy, weird, and eccentric characters, and some of them are artificial intelligence. There is a lot of discussion of architecture. Overall, a satisfying read.
