Yaya’s Story is a book about Yaya Harouna, a Songhay trader originally from Niger who found a path to America. It is also a book about Paul Stoller—its author—an American anthropologist who found his own path to Africa. Separated by ethnicity, language, profession, and culture, these two men’s lives couldn’t be more different. But when they were both threatened by a grave illness—cancer—those differences evaporated, and the two were brought to profound existential convergence, a deep camaraderie in the face of the most harrowing of circumstances. Yaya’s Story is that story.
