Book excerpt: The successful but lonely daughter of a powerful New York theater icon falls for her childhood imaginary friend in this touching love story. As a little girl, Jane has no one. Her mother, a powerful Broadway producer, makes time for her only once a week, for their Sunday trip to admire jewelry at Tiffany's. Jane has only one friend: a handsome, comforting, funny man named Michael. He's perfect. But only she can see him. Years later, Jane is in her thirties and just as alone as ever. Then she meets Michael again-as handsome, smart and perfect as she remembers him to be. But not even Michael knows the reason they've really been reunited. Sunday at Tiffany's is a love story with an irresistible twist, a novel about the child inside all of us and the boundary-crossing power of love.
