Tommy Orange had never read a book about what it means to be a Native American in a big city. In a conversation with The New Yorker’s fiction editor, Orange says that urban Native writers like himself—he is a member of the Cheyenne and Arapaho tribes of Oklahoma, and grew up in Oakland, California—may feel their own experience to be inauthentic, compared to stories set on the reservation. Orange’s début novel, “There, There,” follows a small cast of Native characters whose lives converge at a powwow at the Oakland Coliseum. Plus, Vinson Cunningham on the particular joys of a New York wedding, complete with metal detectors.
