Emma March was only doing her job caring for the late Valentino Fiorenza. She expected no mention in his will, let alone a stipulation to marry his son! But financially, she's desperate... Rafaele will treat Emma like the money-grubbing harlot he think she is. He'll wed her, bed her and destroy her. But then he discovers his new wife is a virgin! He's forced an innocent woman down the aisle.
