Is the narrator telling the story from a third-person point of view?

In The Magician's Nephew, Lewis writes in a third person omniscient perspective. The narrator is not a part of the story, although he does address the reader at several points in the story. This narrator is privy to the thoughts and feelings of Digory and Polly, in particular. The reader is able to especially see the sadness, hope, and temptations of Digory. By knowing Digory's thoughts, one can recognize the motivations behind his actions, and also how he feels about the events in Narnia.
