A Reader's Companion to the Hobbit and the Lord of the Rings
Isaac Asimov
Nice book compiling some magazine articles on the Tolkien books from around when they came out, including several written by luminaries (CS Lewis, Isaac Asimov, Ursula K. LeGuin). I mostly read this because it was a very short book I had hanging around that I hadn’t read, and we’re trying to get rid of most of our books before moving. It was definitely nice to be back in the world of Middle-Earth for a while, even at one remove. And although the writers have different perspectives, I found myself agreeing with each of them while I was reading them!
