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?

Genuinely good people are like that. The sun shines out of them. They warm you right through.

For me,the greater part of writing is daydreaming, dreaming the dream of my story until it hatches out-the writing down of it I always find hard.But I love finishing it,then holding the book in my hand and sharing my dream with my readers.

Perhaps it is partly that we need to love books ourselves as parents, grandparents and teachers in order to pass on that passion for stories to our children. It's not about testing and reading schemes, but about loving stories and passing on that passion to our children.

Our great problem, is that children now know whatever they want to know - at the press of a button they can discover all horrors of the adult world. They know very early on that the world is sometimes a very dark, difficult and complex place, and the literature they read must reflect that. Otherwise we're just entertaining them to pass the time.
