I came to fantasy fairly late. For some ten years, I had been happily writing fiction and non-fiction for adults. But I always loved fantasy, whether for adults or young people; and at that particular point in my life, I wanted to try it, to understand it, as part of the process of learning to be a writer. The results were beyond anything I could have foreseen. As I've said often and elsewhere, it was the most creative and liberating experience of my life.
