Starting from a photograph and writings left by her grandmother, acclaimed African-American novelist Thulani Davis goes looking for the “white folk” in her family, a Scots-Irish family of cotton planters unknown to her-and uncovers a history far richer and stranger than she had ever imagined. Her journey challenges us to examine the origins of some of our most deeply ingrained notions about what makes a family black or white, and offers an immensely compelling, intellectually challenging alternative.
