Now, I'm not normally prone to hatchet-job reviews, but ...
This new book looks terrible! The author — an enfant terrible whose day-job is evidently hunting for UFO's, panicking about the end of the Mayan Calendar, and drawing unsupportable connections between the two — claims that The Lord of the Rings is genuine history, not fiction, and that Tolkien must have tapped into some kind of ancient (perhaps extraterrestrial) store of knowledge to write it. And that he can “prove” it.
Check out my Amazon review for more specifics on the author, the book, and its cockamamie claims.
It seems like this new book might be the heir apparent to Gracia Fay Ellwood's Good News from Middle Earth [sic]. Luckily for us, we've had a break of close to forty years since it appeared (and then just as quickly disappeared — let's hope Quest for Middle-earth does the same).
