Turner woke up in a new body with a beautiful woman beside him. They let him recuperate for a while in Mexico, then Hosaka reactivated his memory for a mission more dangerous than the one that nearly killed him. The head designer from Maas-Biolabs is defecting to Hosaka, or so he says. Turner has to deliver him safely, and the biochips he invented - which are of supreme interest to other parties, some of whom are not human.
Count Zero is human. He's just a kid from Barrytown, and totally unprepared for the heavy duty data coming his way when he's caught up in the cyberspace war triggered by the defection. With voodoo on the net and angels in the software, he can only hope that the megacorps and the super rich have their virtual hands full already.
