When I was a kid, I'd go to the African-American section in the bookstore, and I'd try and find African-American people I hadn't read before. So in that sense the category was useful to me. But it's not useful to me as I write. I don't sit down to write an African-American zombie story or an African-American story about elevators. I'm writing a story about elevators which happens to talk about race in different ways. Or I'm writing a zombie novel which doesn't have that much to do with being black in America. That novel is really about survival.
