From a story on lithub.com headlined “Kamila Shamsie on Finding the Perfect Writing Space”:

During my twenties, when I wrote my first three novels, my writing space was not a physical space but a time of day. I was never in one place for more than a few months, each novel written across two or three continents—in a studio while at grad school in Massachusetts, in my family home in Karachi, in short-term rental apartments in London, in junior faculty housing in Central New York. If you’d ask me during those years where I wrote best I would have answered “2 am.”
