It is a near-perfect environment for vampires. They have won. It is their time. Almost every single man, woman and child has been enslaved in vast camps across the globe.

To be free, they need a miracle, they need divine intervention. But Salvation can be a twisted game - one in which they may be played like pawns in a battle of Good and Evil. And at what cost?
