In retrospect, it seems incredible I didn’t anticipate the questions.

My seventh novel, “Everybody’s Son” — about an affluent white couple, their adopted black son, and his search for identity and reconciliation with his past — came to me in a flash of inspiration. I wrote the story in a white heat, in about four months.

So I was unprepared for what interviewers I spoke to about the book asked me: Why, and how, had I chosen to write from the perspective of an African-American protagonist? I hadn’t expected this line of inquiry to come up because, although race and racial identity are central preoccupations of the book, I saw Anton not just as a black character, but as a singular, distinctive character born of my imagination and efforts.

I soon realized I had been naïve. While I might define myself as an American writer, I grew up in India. That means, to many, I’ll always be an Indian-American writer, with all the freight that the hyphen carries.

The assumption by agents, editors and readers was that I would continue writing novels featuring Indian characters or set in India — as I did in my first six novels — even though I have not lived there for over 30 years.
