There were class differences among black people then and there are class differences among black people now. There is still an assumption among many people in American society that being black is its own class, a blanket class. That, I believe, is an erroneous and deeply offensive view.

I started writing the book without realizing I was writing a book. That sounds stupid, but it's true. I'd been trying and failing to make a different manuscript work, and I thought I was just taking a break by writing some short stories. I'm not a very good short story writer - the amazing compression that is required for short stories doesn't come easily to me. But anyway, I thought I'd try to write some short stories. And a structure took shape - I stumbled upon it.

I really, deeply believe in the primacy of character. I believe that my job as a writer is to put a believable human being on a page.

I think a lot about race and the burdens of representation. There's an idea that because I'm writing a book set around the time of the Great Migration, and happen to be black, I'm trying to write a definitive account of the Great Migration, the so-called "black experience." That's not what I'm doing, and it can be frustrating.

I've been writing all my life. Even though I didn't have sort of careerist aspirations as a writer, it was very much my identity.

Certainly I had from an early age a sense of the power and beauty of religious texts - the awesome magnitude of the Bible stories I was reading as a child. The hymns. The sermons. I can still vividly hear the sermons and the pieces of soft piano music played after them, the preacher asking if anyone wanted to come up to the altar and accept Christ as their savior.

There is a forgotten black middle class in America - a group which is huge but underrepresented in the media and in art. It's difficult to talk about these things, because it forces one to talk in generalities, but that's my view. I do think the idea of a blanket class for black people is unfortunately still present.
