“Render unto Caesar what is Caesar’s, and to God what is God’s.

—Jesus of Nazareth

Death Is Guaranteed

The assassination of Caesar’s chief astrologer explodes into revelations of a secret order known as Dominium Dei or “Rule of God.”  The Dei has penetrated the highest echelons of the empire.  Its mission: to fulfill a decades-old prophecy predicting the exact day and hour the emperor Domitian will die.

Desperate to prove the oracles wrong, Domitian kills any and all suspected enemies.  No one from slave to senator can escape his reign of terror.

Enter the innocent playwright Athanasius. Wrongly accused by jealous rivals of being Chiron, the elusive mastermind behind the Dei, he is condemned to certain death in the scripted “reality” of the arena.

Against all odds he escapes, but he will be hunted to the ends of the earth.  His last hope of refuge is inside the ranks of the Dei. Once in, however, there’s no way out.  The only way to rise—and survive—is to kill and kill again.

DOMINIUM DEI is an action-packed conspiracy thriller from New York Times bestselling novelist Thomas Greanias, one of the world’s leading authors of adventure.  A former journalist and on-air correspondent for NBC, Greanias infuses his thrillers with provocative issues that could be ripped from tomorrow’s headlines.

“I am Caesar. Caesar is God. Therefore, I am God.”

— Emperor Domitian
