"Glow is not gone. Glow remains. Glow is alive. The nanotech drug is now everywhere. It creeps across the world, a mind-bending plague, a brain-altering poison that lives on from host to host, twisting everyone to its will. Still recovering from his addiction, Rex remains in hiding, battling the voices in his head that are not all his own. Some days are peaceful, others are downright terrifying. But there are bigger problems to face--a new alliance threatens the balance of power in the world again, and a dangerous enemy from Rex's past tracks him down. Can Rex really be the cure for the plague that Sisters promised him, or the root of humanity's downfall? Faced with ultimate destruction, Rex must decide if he really is a prophet... or just a coward."--Page 4 of cover.
