Jackie and Skate are two sisters, under whose masks it is easy to recognize Jackie Kennedy and Lee Radziwill, two socialites of the last century, eaters of men and seekers of great fortunes. In her declining years, Skate, more beautiful, elegant, but less favored by fate than her sister, leafing through a family album, tells the story of her life to a journalist. After all, what is it like to have a sister? It means to love, to compete, to hate. Written in a frank and ironic manner, the novel, which mixes real and fictional facts, shows from an unexpected side the life of various high society people in the 60s.
