Are you looking for Nemo, or are you looking for no-one?
Gordon (or 'Nemo' as he's known in a variety of internet chatrooms) finds himself rudely awakened to the reality of his mundane existence. It turns out that far from being a workaday Database Coordinator, he is the inadvertent slave of Evil Machine Intelligences(TM) who are keeping his body sealed in a virtual-reality pod whilst distracting his mind with an elaborate virtual world. He, like the bulk of humanity(but not you, because you're reading this book which is about this world being a virtual world and how could that happen?), is trapped in the McAtrix.
But his awakener, the leader of the human resistance (the virile though small-framed Smurpheus) wants to do more than just free Nemo from this illusion. He thinks Nemo may be special. He thinks that Nemo just might be the No One, the nonentity whose ego is so insignificant it can confront the celebrity-obsessed McAtrix on its own terms and bring it down.
