The Way of the World (Rebeck) - Theresa Rebeck

A good-hearted heiress has become prey to the attentions of an amoral party boy. After he callowly seduces her aunt, making the older woman a figure of public ridicule, their romance is dead in the water. But his insistence on winning back the moneyed heroine fuels the summer's gossip in the land of the one percent.
