In the winter of 1953, Boy Novak arrives by chance in a small town in Massachusetts, looking, she believes, for beauty--the opposite of the life she's left behind in New York. She marries a local widower and becomes stepmother to his winsome daughter, Snow Whitman. A wicked stepmother is a creature Boy never imagined she'd become, but elements of the familiar tale of aesthetic obsession begin to play themselves out when the birth of Boy's daughter, Bird, who is dark-skinned, exposes the Whitmans as lightskinned African Americans passing for White. Among them, Boy, Snow, and Bird confront the tyranny of the mirror to ask how much power surfaces really hold.
