In the Obama era, as Americans confront the enduring significance of race and heritage, this multigenerational account of family secrets promises to spark debate across the country. Daniel J. Sharfstein's sweeping history moves from eighteenth-century South Carolina to twentieth-century Washington, D.C., unraveling the stories of three families who represent the complexity of race in America. Identifying first as people of color and later as whites, the families provide a lens through which to examine how people thought about and experienced race and how, for them and America, the very meanings of black and white changed. The Invisible Line cuts through centuries of myth to transform the way we see ourselves. - Publisher.
