"Situated deep in the Sahara Desert, New Cairo is a city built on technology--from the huge, life-giving solar panels that keep it functioning in a radically changed, resource-scarce world to the artificial implants that have resolved nearly all of mankind's medical problems. But it is also a divided city, dominated by a handful of omnipotent corporate dynasties. And when a devastating new computer virus begins to spread through the poorest districts, shutting down the life-giving implants that enable so many to survive, the city begins to slide into the anarchy of violent class struggle. Hiding amid the chaos is Zala Ulora. A gifted hacker and fugitive from justice. Her fervent hope is that she can earn her life back by tracing the virus and destroying it before it destroys the city--or before the city destroys itself" --
