The Reckoning — Thomas F. Monteleone

The previous Pope died in his arms, blessing him with his last breath. He can perform miracles. His mother was a virgin. His DNA came from the Shroud of Turin. Peter Carenza is the fulfillment of an ancient prophecy and a secret, Vatican-sponsored experiment. But is he the Second Coming, or something far, far worse? Believers the world over hail Carenza as the new Pope and rejoice as he creates a new church for the new millennium. A few people know the truth-that mixing science with the works of God has created not a Saviour but the Anti-Christ.
Now the latest--and last--Pope scours the world for the human guardians of the Biblical seven seals, which must be destroyed before the final cataclysm can begin. Opposing him are a lone Archbishop, the female American journalist who chronicled Carenza's rise to power, and Peter's mother, a nun who truly hears the Word of the Lord.
