The later third of this book was pretty fuzzy to me as I haven't read the Silmarillion in ages and have read little of the History of Middle Earth by Christopher Tolkien but I have read The Lord of the Rings and the Hobbit many times. It was fascinating to read about the role of maps in Tolkien's work and to refresh my memory about the geography and history of Middle Earth. Wonderful illustrations and great maps make this a must read for Tolkien fans.
