My review over at ff.net got so massive that I'll move some of it over here. I opened Notepad and kept a running review while reading Ch 9, which gives me a much longer review than if I finish reading and then try to recapture what I ought to say.
So, two sections from my review that I post here instead of at ff.net.

The Director is right, to some extent, about the Pevensie's less than brilliant background. "uneducated, poorly capitalized, no family, no history." I would say that he underestimates Narnia, though - "a tiny land that depended on luck, magic, and the provenance of the Divine to survive." Or rather, he underestimates the provenance of the Divine - and thus, underestimates "the Narnian children chance had placed on thrones".

Also, you show the us the Narnian sense of kingship. A King serves, first and foremost. He owns the lands and the people, and therefore it is his duty to serve them and protect them. They owe him their allegiance, nothing else, but even that is not a prerequisite for his service.
"How could someone give something and ask nothing in return?"
That's the way the King serves because it is the way Aslan makes himself a servant and a protector of his creations.
