This book is the third of a trilogy. "Montauk Project" is book one and "Montauk Revisited" the second - I have reviewed both these books. Longer story short, the first contains shocking information but is very disjointed and the second is a rambling mess. I would only ever give Moon a one star for literary style - the five stars here is for content.
This book is the best written of this first trilogy, despite the weakness of unverifiable speculations. Although it starts with the mystery of who actually owns the former military base and the disgraceful conspiracy which first dispossessed the local Native Americans and then continually discriminated against them, it doesn't really offer much about the depraved Montauk Project itself even though it also ends with a little about the Montauk Underground/Boys/Transmissions. In between, it links certain shapes discovered at Montauk Point with the basic genesis of life, sacred geometry, Eyes of Horus, pyramids in Egypt and the Tibet/China border, power grids, Sirius (apparently = worship of the light of creation), the moon calendar/menstrual blood, and even a brief history of catholics vs phrees/freemasons and short chapters on the nazi/haushofer/crowley connections.
The best part of the book for me was a number of long-veiled esoteric mysteries and pieces of "lost wisdom" carefully linked together and explained simply and clearly, such as the squared circle and three-dimensional octahedron, piercing the veil, the power of the vesica pisces shape, Bast (a carefully hidden cat/lion/mother goddess, also the goddess of sexual magick/lust whom Moon claims the Sphinx was based on) and sexual ritual. I thought the author was incorrect in quite a few places - but that's just my view against his and he really has done much research and reached many insights which he generously shares. Fascinating.
P.S. This third book was followed by another 4 books: "The Black Sun", "Synchronicity and the Seventh Seal", "Montauk Book of the Dead" and "Montauk Book of the Living". Having now read all seven books, I would suggest reading "The Montauk Project" (the first of the series, which contains shocking information but is very disjointed), "Synchronicity and the Seventh Seal" (the most edifying of the middle books), and "The Montauk Book of the Living" (the last book, which is amazing). One caution: the books are all irritatingly badly written, but the clearly explained occult information justifies the effort.
