Antonia Locke longs to be slender like her pretty sister, but she is too plump for the ton. That is why she is shocked when Patrick Fairchild, the Duke of Exton, suddenly seems interested in her. She has no idea that he wants to seduce her . . . into posing au naturel for one of his paintings. No one, beyond his household, knows of his love for painting, which is hardly a proper pastime for a duke. But if he can finish this one, he will be happy. All he needs is for Antonia to pose for him, but how can he convince the proper daughter of the village's schoolmaster to agree? Marriage. He will marry her, paint her portrait, and then live separately from her once she has given him an heir. After all, many men do that, but one thing he can't imagine being in the picture-falling in love with his model-turns his plans toward a model marriage.
