Art and literature are supposed to be color-blind, of course, but there’s no escaping the fact that the vast majority of literary prizes are presented by white people to white people. Thus the necessity of the Hurston/Wright Legacy Awards, which annually honor the best of black literature. This year’s prizes were handed out last week: “In the debut fiction category, Purple Hibiscus, the story of a Nigerian teenager growing up in a rich and troubled family, by Chimamanda Ngozi Adichie; in nonfiction, In Black and White: The Life of Sammy Davis, Jr. by Wil Haygood; and in the fiction category, Hunting in Harlem, the tale of three ex-cons in contemporary New York, by Mat Johnson.”
