In The Voyage of the Dawn Treader Lucy discovers a magic book and reads a story which she cannot remember after she finishes it, but she always longs to hear again. Its so interesting to think of story as a category of thought for heavenly longings.
“Oh, what a shame!” said Lucy. “I did so want to read it again. Well, at least I must remember it. Let’s see . . . it was about . . . about . . . oh dear, it’s all fading away again. And even this last page is going blank. …It was about a cup and a sword and a tree and a green hill, I know that much. But I can’t remember and what shall I do?”
And she never could remember; and ever since that day what Lucy means by a good story is a story which reminds her of the forgotten story in the Magician’s Book.
[Then later during her conversation with Aslan:]
“Child,” said Aslan, “did I not explain to you once before that no one is ever told what would have happened?”
“Yes, Aslan, you did,” said Lucy. “I’m sorry. But please-”
“Speak on, dear heart.”
“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. We must meet the master of this house.”
