1886, New York City: Charlotte Gleason, a rich heiress from England, escapes a family crisis by traveling to America in order to marry the even wealthier Conrad Tremaine. She soon decides that an arranged marriage is not for her and persuades her maid, Dora, to take her place. What begins as the whim of a spoiled rich girl wanting adventure becomes a test of survival amid poverty beyond Charlotte's blackest nightmares. As for Dora, she lives a fairy tale complete with gowns, jewels, and lavish mansions--yet is tormented by guilt and the presence of another love that will not die. Will their masquerade be discovered? Will one of them have second thoughts? There is no guarantee the switch will work. It's a risk. It's the chance of a lifetime.
