Crystal and I just finished reading Till We Have Faces by C.S. Lewis. I would not recommend going into it thinking that it is a sequel to the Narnia Series. That could prove disastrous. It was, however, very insightful. Some of the topics addressed were jealousy, selfishness, modernity and its deceptiveness, desire of a human (here Orual) to envelop another's life, and many other lesson which would merit our thought.
The key, I think, to the whole book is understanding this quote made in the final pages of the work: "Of the things that followed I cannot at all say whether they were what men call real or what men call dream. And for all I can tell, the only difference is that what many see we call a real thing, and what only one sees we call a dream. But things that many see may have no taste or moment in them at all, and things that are shown only to one may be spears and water-spouts of truth from the very depth of truth." (Orual in Till We Have Faces, 277)
