The simple fact of being a human being is you migrate. Many of us move from one place to the other. But even those who don't move and you stay in the same city, if you were born in Manhattan 70 years ago, you're born in Des Moines 70 years ago, you've lived in the same place for 70 years, the city you live in today is unrecognizable. Almost everything has changed. So even people who stay in the same place undergo a kind of migration through time. And in the novel, what I'm trying to explore is how everyone is a migrant.
