In Invisible there's a lot about childhood, the death of the brother and then the relationship between the brother and sister.

Money, of course, is never just money. It's always something else, and it's always something more, and it always has the last word.

I feel that the act of writing, in and of itself, is a tool towards probing that which you wouldn't without that pen in your hand. It's a strange, almost neurological phenomenon, and the words seem to generate more words - but only when you're writing. You can't do it in your head.

Memory and the imagination are almost identical. It's the same place in the brain and the same thing is happening. When you think about your own life, there are no memories without place. You are always situated somewhere. I think the imagination - the narrative imagination at least - situates you in a specific space when you start to think of a story. I often use places I know. I put my characters inside rooms and houses that I'm familiar with - sometimes the houses of my parents or grandparents or previous apartments I've lived in.

Most of the boys would come with bits of equipment that their fathers had given them from their war days - helmets, canteens, binoculars, these kinds of things - that leant a kind of authenticity to the games we were playing. But, of course, my father never gave me anything. So I began to question him. You know, Why don't you have anything from the war? And I think he was...embarrassed to tell me he hadn't fought, because, you know, little boys want to turn their fathers into heroes, and he didn't want to be diminished in my eyes.

A here exists only in relation to a there, not the other way around. There's this only because there's that; if we don't look up, we'll never know what's down. Think of it, boy. We find ourselves only by looking what we're not. You can't put your feet on the ground until you've touched the sky.

Fiction creating reality.
