**This book is out of print and no longer available. I've rewritten and re-edited the novel and have re-released it as GHOSTS OF TOMORROW. There are several new scenes, and a new ending.*** The dream of Artificial Intelligence is dead and the human mind is now the ultimate processing machine. Demand is high, but few are willing to sacrifice their lives to become computers. Black-market crèches, struggling to meet the ever-increasing demand, deal in the harvested brains of stolen children. But there is a digital snake in that fractally modelled garden; some brains make better computers than others.
