What a brilliant read! I'm not a big fan of all these books that jump on the Da Vinci Code bandwagon, and thankfully, this is not one of them. The characters are fantastic, the plot - seamless and the idea of something of this magnitude being found by accident, utterly intriguing. I was completely immersed in the story and caught myself, more than once looking over my shoulder in case I too was being followed. Irrational, I know, but surely the sign of an excellent book.
