There are some themes, some subjects, too large for adult fiction; they can only be dealt with adequately in a children's book.

I think it's perfectly possible to explain how the universe came about without bringing God into it, but I don't know everything, and there may well be a God somewhere, hiding away. Actually, if he is keeping out of sight, it's because he's ashamed of his followers and all the cruelty and ignorance they're responsible for promoting in his name. If I were him, I'd want nothing to do with them.

All the stories of the Bible that I know came to me first from my grandfather's lips... He would see stories in everything. He told stories very easily and very generously, so I loved him for that. He was a simple man, a Victorian; he was born in 1890-something. He saw no reason and had never seen any reason to question his Christian faith. His faith was strong and simple and that's it. And I, like his other grandchildren and the children in his parish, sheltered underneath it.

Men and women are moved by tides much fiercer than you can imagine, and they sweep us all up into the current.

Gradually, at various points in our childhoods, we discover different forms of conviction. There's the rock-hard certainty of personal experience ("I put my finger in the fire and it hurt,"), which is probably the earliest kind we learn. Then there's the logically convincing, which we probably come to first through maths, in the context of Pythagoras's theorem or something similar, and which, if we first encounter it at exactly the right moment, bursts on our minds like sunrise with the whole universe playing a great chord of C Major.

She was riding a bear! And the Aurora was swaying above them in golden arcs and loops, and all around was the bitter Arctic cold and the immense silence of the North.

I write almost always in the third person, and I don't think the narrator is male or female anyway. They're both, and young and old, and wise and silly, and sceptical and credulous, and innocent and experienced, all at once. Narrators are not even human - they're sprites.
