I'm trying to write a book about what it means to be human, to grow up, to suffer and learn. My quarrel with much (not all) fantasy is it has this marvellous toolbox and does nothing with it except construct shoot-em-up games. Why shouldn't a work of fantasy be as truthful and profound about becoming an adult human being as the work of George Eliot or Jane Austen? Well, there are a few fantasies that are. One of them is Paradise Lost.
