I'm always keen to check out crime/sci-fi genre blending, and so this police procedural set in 2050 Los Angeles caught my eye. I'm not a deep reader of speculative fiction, but it's often struck me that near-future sci-fi struggles to get both the macro and micro stuff right. That is to say either the large-scale geopolitical context is interesting, or the human-scale tech/social vision is interesting, but few authors are able to maintain control over both. This is a pretty good example of a book with that balance issue. The background is that India and China have destroyed each other in nuclear war, and the skyscrapers of downtown Los Angeles are now gang-controlled tenements stuffed to the gills with Indian refugees. Meanwhile, America seems to have splintered into several zones, and leaving the confines of Los Angeles means leaving the rule of law.
All of which is fine except that it's hard to imagine a scenario in which a splintered America would be opening the doors to huge numbers of refugees, or that the typical middle-class Los Angeles lives would continue in such a future, or that there could be celebrity musicians or sports stars in such a world. There are just basic things like food supply and transportation that would be completely upended, much less mass entertainment. But if you can set aside the impossibilities of the macro setting, the actual police procedural investigation of a murder is pretty good.
The idea is that in 2050, there are cameras literally embedded everywhere, and everything is recorded, and the police have access to all of it. So when there's a crime like the murder that kicks things off, they can enter a VR simulation that reconstructs the scene of the crime and they can play with all manner of data to ID the killer. Except in this case, the murder takes place in a dead zone with no camera coverage, and the suspect is wearing a dust mask and a hoodie... The story follows LAPD Detective Terri Pastuzka as she in driven around the physical Los Angeles (all cars are self-driving and all linked to a massive network, which allows cop cars to "zipper" through traffic at high speeds) and pilots herself through augemented and virtual Los Angeles to solve the murder.
For cops, with their special "PanOpts" (panopticon) headsets, everyone appears tagged with basically any information that might exist in a database. There is no more privacy, and it's all so eerily plausible. In the same vein, video footage is constantly remixed and remade, and there's very little to distinguish real from fake any more, and indeed, it takes "fake news" to creepy new deepfake heights. As Det. Terri follows leads from murder to murder, the pace picks up and the story starts to get dizzying, ending with the kind of plot twist that some readers will probably hate, but is the only possible solution.
