I read this as a favor to a friend who gave me the book. Frankly, I found it ridiculous. The artifacts on Mars and the moon I find rather unbelievable,but it's the part where he tries to tie in the Kennedy assassination where he really lost me. He doesn't even attempt to explain why Oswald would be involved in a conspiracy involving alien ruins on the moon, which might have at least upped the entertainment factor. Instead there was an overabundance of shifty math and pseudoscience. The book was too dull to be entertaining and too nonsensical to be taken seriously. I do enjoy seeing the pictures of the moon and Mars, so those were cool.
