Fantastic cyberpunk thriller that takes place several years in the future mostly in recently Great Britain-free Edinburgh, Scotland. It deals with the investigation of a theft inside a popular MMORPG called Avalon Four. The story unfolds with each chapter told from the perspective of one the three main characters (the cop, the librarian and the nerd): Sue, a sergeant who is first on the scene and does a lot of the ground work for the investigation; Elaine, a forensic accountant who is brought in for insurance purposes to investigate the robbery; and Jack, a geeky programmer/gamer who is brought in as a consultant to Elaine's company. 
 The main protagonist of the story was the element that made it cyberpunk, the technology, the driverless taxis, the game play and especially the glasses, those wonderful glasses that everyone wore, the cops with their Copspace; the gamers and Spooks with their augmented reality, and everyday citizens with their visual maps and instant emails/social updates. What Google Goggles hopes to one day be. 
 The second person narrative was a bit confusing at first and sometimes even throughout if you forgot whose chapter you were reading, but overall seemed to work well for the story. And, some of the words and language I was never sure whether they were new cyberpunk words that the author invented or just British slang. I am sure a mix of both. But Stross has a writing style that effectively moves the story along and his character descriptions are full of wit and insight, i.e. (view spoiler)[ describing one of the more interesting characters Inspector Liz Kavanaugh: "...with her sharp suits and her degrees in criminology and social science isn't so much climbing the greasy pole as riding up it on a personal jet pack; not so much a straight arrow as a guided missile aimed at making chief constable. If she's going all swivel-eyed on you and muttering about spies and cloak-and-dagger stuff, but hasn't gone completely off the deep end...then you bloody ought to keep your eyes peeled for secret agents doing the funny handshake two-step down by the water of Leith." (hide spoiler)] 
 Although I thought the infodump at the conclusion of the book that ties up all the loose ends was maybe a bit unnecessary and lazy, overall I was thoroughly entertained by this well done cyberpunk whodunit.
