Jonathan Lethem’s Gun, With Occasional Music is a scifi noir story very heavy on the noir. In a world with uplifted kangaroos and apes and accelerated-development babies, Conrad Metcalf is trying to solve a murder. And then another and another. He’s an ex-cop and has his custom drugs to keep him feeling the exact right level of ennui and tenacity, while the victims and witnesses take drugs to forget. It’s pretty great.
One of the things I really like about the book is the dual economic systems going on. There’s money and there’s karma. Karma is what the cops take away when you do bad things, and what you get given when you’re a model citizen. It’s a bit more centralized than Cory Doctorow’s Whuffle but you can see the connective strands. The thing is that when your karma hits zero you go into a freezer, and are removed from society for a while, which makes my favourite part of the book possible.
[SPOILERS] About 3/4 of the way through the book Conrad pisses off enough people he gets tossed in the freezer for six years. This is awesome for the story because when he gets out it’s like that time passed overnight. He’s even more dogged about solving his case now that everyone else has had years to deal with the aftermath. [/SPOILERS]
So yes, definitely recommended especially if you liked George Alec Effinger’s When Gravity Falls
