Andrew, the young comparative religions professor from Book I, knows what he needs to do. He needs to give the still sleeping Adam flesh, by mating with a young and mysterious Middle Eastern woman known as Mara. The time is right at last, so what can possibly stop Andrew and Mara from coming together in fulfillment of prophecy? Well, for one thing, there's Michael.

And then there are those who follow Michael, the great archangel who's made it his mission to keep humanity in its current ignorant and deluded state. Ranged on the looming battle's other side are Mantrella, Bringer of Light, and those who follow him.

Meanwhile, Earth itself convulses as its inhabitants endure the plagues of Revelation. Will those who can stop Michael act in time? And even if they do, will they prevail?
