These books are magical. A person can read them over and over, and they never lose their poetic beauty. Tolkien is not merely a writer, he's a master crafter of words, able to create whole worlds with finesse. One merely needs to turn to the pages of Lothlorien and its beautiful Mallorn trees with trunks shining with silver and a bouquet of leaves made of gold in order to see what I'm talking about. 
 There is so much found in these books, you could easily have hour long discussions about them. You can grab senior theses out of these books as if out of a hat. It really goes without saying, I don't have to recommend this book, it should prove worthy enough on its own.
