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 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 couldn't imagine a book with many characters in it and one of them not being gay. It would have felt like a glaring and problematic omission for me. But I also wanted to write that character as a person, not just a gay person.

By sixteen I thought, "Ah, this is all crap, you're all sheep, I'm not going to church, leave me alone." And then at a certain point in my teens I started to go to Catholic churches, by myself. Not because I wanted to be Catholic, but because I wanted to light a candle and say something like a prayer and just sit there. There was something I was missing or trying to reconnect with. But it was a secret at the time. I'd developed this cynical persona and the last thing I wanted to admit was that I was skulking around churches in my spare time.

At some point I just acknowledged, at least to myself, that I had a great deal of respect for people of faith. Faith is a strange and wonderful thing. You come up to a kind of wall of unknowing and instead of turning back in despair you leap over it into something else. The Church isn't why I'm a writer, but it's probably a part of it.

I think of my success as a kind of fluke. How else could I possibly think of it? And although it's a banal thing to say, I wrote my book because I was writing my book. At first I didn't know I was writing it, and one of the amazing things that happened as I was putting sentences down on paper is that some of the things that are most sacred and important to me rose to the surface of the prose.

One of the things that writers worry about is finding a voice. I don't think it's a thing that you find so much as it is something that comes to you, or that presents itself.
