Aurelia Rubbini, the only child of a rich merchant in fourteenth century Italy, has been raised to be a dutiful daughter, wife and mother, but she longs for something more than the restricted life intended for her. Then one day, her father brings home from a buying trip an Asian slave boy, Batu, who will reshape Aurelia’s destiny.
Aurelia and Batu are inexorably drawn to each other, but their relationship is forbidden as Aurelia is destined for an arranged marriage to further her father’s political ambitions. When Aurelia marries Lorenzo de Graziano, a nobleman with a dangerous reputation, Batu insists on going with her for her protection. But Batu’s presence arouses violent passions that Aurelia, in her innocence, can never understand.
