Brimming with rich, electrifying tales of the precious dye and its ancient heritage, Indigo is also the story of a personal quest: Catherine McKinley is the descendant of a clan of Scots who wore indigo tartan; Jewish "rag traders"; a Massachusetts textile factory owner; and African slaves - her ancestors were traded along the same Saharan routes as indigo, where a length of blue cotton could purchase human life. McKinley's journey in search of beauty and her own history leads her to the West African women who dye, trade, and wear indigo - women who unwittingly teach her that buried deep in the folds of their cloths is all of destiny and the human story.
