This is the third book by these authors - The Hiram Key and The Second Messiah were the others.
I have to confess that I was not impressed by their previous two titles; while I acknowledge that they were read enthusiastically by many masons and the general public.
However, there is a lot in this effort that impressed me.
It is subtitled 'The Prehistoric Technology that Survived the Flood', and that is a pretty accurate description of the contents.
