The Lord of the Rings is my favorite book, and The Two Towers might be my favorite volume of it.

Considering this book is primarily concerned with languages that don't actually exist (in the sense that a culture-group speaks it naturally), it is nevertheless one of the best introductory books on linguistics that I've read.

Gets a bit rambley, but ultimately swings back around to “hey, linguistics is important because people are important, and people communicate with language.” But it's very readable and does what it set out to do: tell us what linguistics is and why it's important.

This book is such a comfort and joy, and I love it more every time I read it. Easily my favorite part of my favorite novel; and the novel that I think is the greatest of any book I've read. The Lord of the Rings is so incredibly special.

Useful for what it is, if a bit poorly laid out. The more famous second edition is better.
