Ασ afflicted by classic paranoia, the self-styled Master and God sees enemies everywhere. As he vents his suspicions, no one is safe. A reluctant hero, Gaius Vinius Clodianus is hand-picked for high rank in the Praetorian Guard, a brave man striving for decency in a world of corruption and deceit. Flavia Lucilla, tending the privileged women at court, hears the intimate secrets of a ruler who plays with the lives of his subjects as if he were indeed a careless god. In the dark shadow of Domitian's reign, Clodianus and Lucilla play out their own complex tale of resilience, friendship and love. Unwilling witnesses to Domitian's descent into insanity, these ordinary people must choose between their sworn duty to protect the Emperor and an act of courage that will change the future of Rome.
