A notion for a story is for me a confluence of real events, historical perhaps, or from my own memory to create an exciting fusion.

Wherever my story takes me, however dark and difficult the theme, there is always some hope and redemption, not because readers like happy endings, but because I am an optimist at heart.

I tell you, my friends,’ he said one day. ‘I tell you that I am the only sane man in the regiment. It’s the others that are mad, but they don’t know it. They fight a war and they don’t know what for. Isn’t that crazy? How can one man kill another and not really know the reason why he does it, except that the other man wears a different colour uniform and speaks a different language? And it’s me they call mad!

Anything that gets children reading is fine.

I don't know, but I do think that everyone has a story to tell. The question is, can they find the voice and the confidence to tell it? We lack the encouragement as young people to believe this; we very often think that writing is for clever people, which it isn't.

There is the myth that writing books for children is easier than writing books for grownups, whereas we know that truly great books for children are works of genius, whether it's 'Alice in Wonderland' or the 'Gruffalo' or 'Northern Lights.' When it's a great book, it's a great book, whether it's for children or not.
