Already an underground sensation, a high-tech thriller for the wireless age that explores the unthinkable consequences of a computer program running without human control a daemon designed to dismantle society and bring about a new world order. Technology controls almost everything in our modern-day world, from remote entry on our cars to access to our homes, from the flight controls of our airplanes to the movements of the entire world economy. Thousands of autonomous computer programs, or daemons, make our networked world possible, running constantly in the background of our lives, trafficking e-mail, transferring money, and monitoring power grids. For the most part, daemons are benign, but the same can't always be said for the people who design them. Matthew Sobol was a legendary computer game designer; the architect behind half-a-dozen popular online games. His premature death depressed both gamers and his company's stock price.
