In New York City the dead walk the streets, driven by an insatiable hunger for all things living. One among their hordes is different: though he shares their appetites he has retained his human intelligence. Alone among the mindless zombies, Gary Fleck is an eyewitness to the end of the world. From the other side of the planet a small but heavily-armed group of young girls turned soldiers has come in search of desperately needed medicine. Dekalb, a former UN weapons inspector, will lead them as their local guide. Ayaan, a crack shot at the age of sixteen, will stop at nothing to complete her mission. They think they are prepared for anything. On Monster Island they will find that there is something worse even than undeath... while Gary learns the true price of survival.
