"[While reading the Magician's book, Lucy] came to a spell 'for the refreshment of the spirit.' The pictures were fewer here but very beautiful. And what Lucy found herself reading was more like a story than a spell. . . When she had got to the third page and come to the end, she said, 'That is the loveliest story I've ever read or ever shall read in my whole life. Oh, I wish I could have gone on reading it for ten years. At least I'll read it over again.'
But here part of the magic of the Book came into play. You couldn't turn back. The right-hand pages, the ones ahead, could be turned; the left-hand pages could not . . . . and it was all fading away. 'How can I have forgotten? It was about a cup and a sword and a tree and a green hill, I know that much.'
'Shall I ever be able to read that story again; the one I couldn't remember? Will you tell it to me, Aslan? Oh do, do, do.'
'Indeed, yes, I will tell it to you for years and years. But now, come . . . .'"
