The core of the book examines The Lord of the Rings as a linguistic and cultural map and as a response to the meaning of myth. It presents a unique argument to explain the nature of evil and also gives the reader a compelling insight into the unparalleled level of skill necessary to construct such a rich and complex story. Shippey also examines The Hobbit, explaining the hobbits' anachronistic relationship to the heroic world of Middle-earth, and shows the fundamental importance of The Silmarillion to the canon of Tolkien's work. He offers as well an illuminating look at other, lesser-known works in their connection to Tolkien's life.
