This book mixes Egyptology with New Age. While it summarises the main theories both mainstream and fantastical about the Great Pyramid very well, it champions a theory leaning towards New Age. The first two chapters provide a broad overview over the most significant and well-known theories about the Great Pyramid as well as a thorough description of its exterior and interior: measurements, location, … The connection between the alignment of the Great Pyramid and astronomy is also very interesting. However, chapter 3 and 4 are purely speculative and seem to be based more on New Age theories. All in all, it provides an easy light read.
