What sets this apart from other books such as 'The Jesus Mysteries' or 'The Arcadian Cipher' is the depth of research put into the subjects. Mr Gardner adds weight to Barbara Theiring's work 'Jesus The Man' but continues on, not only providing the bloodline of Jesus/Magdelene and his borhter James (aka Joseph of Arimethea)... thorugh other 'legendary' names such as King Arthur, The Crusades, association to Rennes-le-Chateau, The line of Stuarts, Freemasonry etc... in a tour-de-fource of chronology.
One must take care to read between the line, as i found it easy to read and digest as FACT... i would suggest that for those who have an interest in these topics, that the overlap in Mr Gardner's research and that of others becomes evident in the text, but where it deviates is clearly Mr Gardner's own hypothesis.. but he puts it so well and constructs all the evidence to back it up you are compelled to believe.
So if you want to know who is heir to the royal bloodline of Christ? or if not... want to know the reasons behind the great Roman Catholic Church cover up of the 'real' Christ teachings IN EXTRAORDINARY DETAIL.. read this book.
To prime yourself, read the books mentioned above beforehand and you will see the difference in this work.
