Angst? What Angst?: Lampshaded — Shasta learns in a single evening that the old fisherman who raised him is not his real father and that the same man plans to sell him as a slave. He's not dismayed about either of these, since 1. he doesn't love the old man and 2. his life is hard labor anyway, so being a slave would be no different and possibly better. What bothers him is that the visitor's horse speaks up and tells him that being his master's slave would be a Fate Worse Than Death.
Cult Classic: The Horse and His Boy is definitely the odd book out in the Narnia series, as it's not part of the primary plot line (instead serving as a side-story taking place during The Lion, The Witch, and The Wardrobe's late Time Skip), does not star any Earth children traveling to Narnia, and can be removed entirely from the series without leaving any holes. And yet, it has a very loyal following who like it because it's the Oddball in the Series.
