West Virginia: A church congregation vanishes in mysterious circumstances, only to be found dead some miles away. The evidence on the ground appears to indicate a ritual killing and the work of demonic forces.

Following the trail from West Virginia to Mexico and Miami, Jessica uncovers a deadly conspiracy that might lead all the way to the Vatican itself. Only with her unique understanding of the powers of deception can they hope to stop a ruthless killer from exacting a revenge that's been thirty years in the planning . . .
