Rapture of the Nerds , co-authored by Cory Doctorow and Charles Stross , is set at the end of the 21st century in a very different Earth where the post-singularity population exists at the bottom of a gravity well.
The story is about a technophobe named Huw, who has just been appointed to serve on the Tech Jury Service (which decides the fate of technology downloaded from the "cloud' that surrounds the earth).
Huw will get thrown in the path of dangerous people, dangerous technology and an annoying technovirus. The technologically focused storyline is balanced with humor and wackiness, religious allusions, holographic djinn, clones, AI constructs and in-jokes for science fiction fans. If you spot the in-jokes drop a comment and let me know!
