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: Lucifer’s advance guard, the Fallen. All of humankind is in imminent danger of being enslaved by the forces of evil. Bravo, Fra Leoni and Bravo’s blind, brilliant sister, Emma, are the first and last line of defense against the chaos unleashed by the Testament of Lucifer.
