Writing a novel is like an amusement park or a museum or a city. You go into that place and you have certain experiences and those experiences, hopefully, have some impact on you.

I think there's really strong social stratification in South Asia.

I think wars, climate change, all that stuff is going to move people. And so I wanted to say, "What if the migration apocalypse occurs and it isn't an apocalypse at all?" Maybe we will still find ways to be happy and for our children and grandchildren to thrive and the world to move on.

Yes, Manila had its slums; one saw them on the drive from the airport: vast districts of men in dirty white undershirts lounging idly in front of auto-repair shops - like a poorer version of the 1950s America depicted in such films as Grease.

Certainly, historically, there has been more attention given in the international media to Indian English-language writers than to Pakistani English-language writers. But that, in my opinion, was justified by the sheer number of excellent writers coming from India and the Indian diaspora.

You know, very often, if you look at the kinds of communications that they're getting in an ISIS recruiting video, the videos that, you know, that one hears of as radicalizing them, these are like action movies. And so in the sense, it's that by closing off the idea that young Muslims and particularly young Muslim men can be American heroes, it increases the chance that they'll try to be some other kind of hero. And that, I think, is entirely counterproductive.

I think the beard helps offset - it's the only hairstyle I can really pull off. But I'm often clean-shaven. I think, you know, for me, it's not that signifier. What's interesting to me though is although the beard isn't a signifier of that to me, other people very often think that it is. And so people in America might react differently. The, you know, border agents might react differently. The guys at airport security might react differently.
