Is it possible that the author of the previous review is a member of Opus Dei? Such blinkered and biting negativity would certainly seem to point in that direction! Either that, or the author prefers to bury his/her head in the sand rather than face up to probable reality.
If you have the courage and intellect to question the teachings of the Roman Catholic Church, 'The Holy Blood and the Holy Grail' will, in all probablity, be the most important book you will ever read. Within its pages, Lincoln, Baigant and Leigh offer the intelligent, questioning reader an alternative - and, in all possibility, correct - account of the history of Christianity and the life of the man commonly known as Jesus the Christ.
I will not hint at what conclusions the authors reach. They are highly controversial, to say the least. It suffices to say that if you are the type of person who prefers to know the truth, then 'The Holy Blood and the Holy Grail' should be essential reading for you. It will certainly change the way you think forever.
(If you have already read Dan Brown's 'Da Vinci Code', now's the time to read the real thing!)
Kind regards
