Archie became absolutely still, afraid that the rapid beating of his heart might betray his sudden knowledge, the proof of what he'd always suspected, not only of Brother Leon but most grownups, most adults: they were vulnerable, running scared, open to invasion.

You seldom get a censorship attempt from a 14-year-old boy. It's the adults who get upset.

He was swept with a sadness, a sadness deep and penetrating, leaving him desolate like someone washed up on a beach, a lone survivor in a world full of strangers.

There are no taboos. Every topic is open, however shocking. It is the way that the topics are handled that's important, and that applies whether it is a 15-year-old who is reading your book or someone who is 55.

There are moments that stop the heart, that catch the breath, that halt the beat of blood in your veins, and you are suspended in time, held between life and death, and you wait for something to bring you back again.

When you get the ideas, that's a thrill; when you're writing the book and it's corning out well, that's a thrill; when you finish it and other people read it, that's a thrill. There are going to be reviews, of course; not everyone's going to love it. You feel sort of naked and vulnerable in a way. That's just a minor part of the process, really. If you can't take that part, you shouldn't be in the business. But there are so many joys to writing.

You have to accept the critical reviews if they treat you with respect. Actually, it's one person's opinion. So, it's a concern but not an overriding one, and I don't stay up nights worrying about reviews. But there are certain people I respect who I hope will like a book.
