Dubbed Interface Zero by those who created it, the Tendril Access Processor—or TAP—downloads the Global DataNet and Hyper Reality directly into the minds of billions of users across the solar system, bringing the world an unparalleled level of interconnectivity … and danger. Malware plagues the Deep, and hackers manipulate the Tendril Access Processor, uploading malicious viruses and stealing secrets and the identities of the unwary. In 2088 a massive solar flare disrupts Earth’s satellite network, leaving the world in chaos as TAPs malfunctions. Hyper Reality overlays are indistinguishable from the physical world, and global rioting makes the whole world a war zone. Behind the madness, two AIs go to war, using humanity as their pawns.
