The Magician's Nephew

The Magician's Nephew is a great setup for the rest of the Narnia books, although on its own, it's not super compelling. I like Polly better as a character (perhaps because she has more common sense), but she ends up sort of relegated to a sidekick for Digory, the titular nephew, and I don't love that. But I really love the way Narnia is sang into being and, of course, the first time we meet Aslan.
