1576. Five years after the defeat of the Ottoman Empire at the Battle of Lepanto, a ship steals unnoticed into Venice bearing a deadly cargo. A man more dead than alive, disembarks and staggers into Piazza San Marco. He brings a gift to Venice from Constantinople. Within days the city is infected with bubonic plague - and the Turkish Sultan has his revenge. But the ship also holds a secret stowaway - Feyra, a young and beautiful harem doctor fleeing a future as the Sultan's concubine. Only her wits and medical knowledge keep her alive as the plague ravages Venice. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
