The Vignes sisters will always be identical. But after growing up together in a small, southern black community and running away at age sixteen, it's not just the shape of their daily lives that is different as adults, it's everything, including their racial identities. Many years later, one sister lives with her black daughter in the same southern town she once tried to escape. Across the country, the other secretly passes for white, and her white husband knows nothing of her past. Still, although separated by so many miles and just as many lies, the fates of the twins remain intertwined. What will happen when their own daughters' story lines intersect?
