When the obituary of Matthew Sobol, a legendary architect of computer games, is posted online, a previously dormant daemon activates, initiating a chain of events that unravels our interconnected world. It recruits, corrupts, and kills. With Sobol's secrets buried with him, and as new layers of his daemon are unleashed, it's up to Detective Peter Sebeck to wrest the world from the grasp of a malevolent, self-replicating virtual enemy before its ultimate, terrifying purpose is realized: to destroy civilization. So far, Daemon is winning.
