(bloomberg) Junot Diaz's ``The Brief Wondrous Life of Oscar Wao'' (Riverhead Books) won the National Book Critics Circle award for fiction, while Edwidge Danticat's ``Brother, I'm Dying'' (Knopf) won for autobiography. Joyce Carol Oates, who was nominated in both categories, won no prizes. It was a good night for the island of Hispaniola at the award ceremony in New York last night. Diaz was born in the Dominican Republic and moved to the U.S. at age 6, while Danticat was born in Haiti and came to the U.S. at 12.
