But when you read a book, what you see are black squiggles on pulped wood or, increasingly, dark pixels on a pale screen. To transform these icons into characters and events, you must imagine. And when you imagine, you create.

I think that we live in a world - and this is something which living in Pakistan, perhaps, has taught me - and, you know, we live in a world where there is a constant feed from social media, the news, etc., of things that can scare us. And we become so anxious because human beings are meant - are designed to be sensitized to dangerous stuff.

We need to start imagining the future or it will get imagined for us, and the ways that it has been imagined thus far don't seem very attractive.

I push against the tree and run away, stumbling, the unreal night playing with me, gravity pulling from below, behind, above, making me fall. And I run through a world that is rotating, conscious of the earth's spin, of our planet twirling as it careens through nothingness, of the stars spiraling above, of the uncertainty of everything, even ground, even sky. Mumtaz never calls out, although a thousand and one voices scream in my mind, sing, whisper, taunt me with madness.

I would have bet money that Britain would not vote to leave the EU, and I would have been wrong. I would have bet money that Trump would not have been the Republican nominee, and I would have been wrong and I certainly would have bet money that he wouldn't win the election.

We keep the negative stuff because it's the negative stuff that's going to, you know, potentially kill us. That fin in the water - maybe it is a shark. That yellow thing behind the tree - maybe it is a lion. You need to be scared.

My dad had this outlook: It doesn't matter what I want to read - reading was a good thing. So whatever I was curious about they'd get for me from the library. Books were a kind of a resistance to reality. I liked to imagine worlds that were different. I still do.
