A great read,it sheds light on Priory Sion and its ties with the Templars.Altenative History regarding Jesus' legacy.It mainly takes place in south of France in the infomous Rennes le Chateaue.Most definately Dan Brown owe some form of debt to these writers.The sequel is even better.It is not a read for those who are not open minded that there might be another side to Christianity.
