A recent MR request asked me which book I wished I had written and now I have a recent answer: Laura Miller's The Magician's Book: A Skeptic's Adventures in Narnia. And I'm not even a big Narnia fan (this review aside). Most of all this is a book about what it means to love another book and how deep such a love can run. It also covers the gap between children and adults, how storytelling works, what theology means in art, not to mention it gives an excellent portrait of Tolkien. Every paragraph of this book offers something of value — how many books can claim that? Bravo, and again you needn't love or even know much about C.S. Lewis.
I'll buy Laura Miller's next book, sight unseen, no matter what the topic.
