Rule 34 and Halting State are breakneck police procedurals set 20 minutes into the future. Charlie Stross has made his authorial mark the imagining of plausible, realistic worlds that push the back of your skull into the wall. They are better written and more speculative than Daniel Suarez’s books set in the future now – but they also deal with harder material.
The plot is so ridiculous and yet perfectly put together that I can’t tell you because you’ll think it’s a crappy stupid idea. I keep typing oblique plot summaries and they all sound like the absolute worst book ideas. You’ll miss out on some really mind-blowing fun writing.
In the most abstract sense Rule 34 (named after the infamous pornography postulate) is a serial killer hunt and Halting State is a heist novel (named after a term in a mathematical problem that breaks the premise that the world is a solvable problem). The biggest criticism is that these are idea novels – you aren’t getting into serious emotional relationships with these characters. If you read a lot of Sci-Fi, you won’t notice, but if you read more literature you’ll probably be annoyed that the emphasis is always on the breathless action.
A fun punchy read and a good sign in someone who’s become a professional prognosticator. You should also check out Charlie Stross’s frequently updated blog, where he regularly bitches about how the future keeps happening and stealing plot points out from under him as he writes.
