In a hidden cave in the mountains of Lebanon, a man makes a fateful discovery. He has been chosen to be the carrier, to bring what has been forbidden for thousands of years out of the darkness and into the light: the Testament of Lucifer.
In Istanbul, Bravo Shaw, head of the Gnostic Observatine sect, has been warned by his ageless confessor, Fra Leoni, of a battle most ancient: the war between Good and Evil, waged to a standstill since time immemorial. Now something has altered the balance of power. An unfathomable danger has arisen: LuciferÃ¢Â€Â™s advance guard, the Fallen. All of humankind is in imminent danger of being enslaved by the forces of evil. Bravo, Fra Leoni and BravoÃ¢Â€Â™s blind, brilliant sister, Emma, are the first and last line of defense against the chaos unleashed by the Testament of Lucifer.
