"When suburban Claudia Kincaid decides to run away, she knows she doesn't just want to run from somewhere she wants to run to somewhere—to a place that is comfortable, beautiful, and preferably elegant. She chooses the Metropolitan Museum of Art in New York City. Knowing that her younger brother, Jamie, has money and thus can help her with the serious cash flow problem she invites him along."
