u cnt cnt take ur eyes of the book!!!!! everything is very unexpected, the book is a series of twists nd turns. dan brown has out done himself. its about a secret organisation in the usa nd how they have a machine by which they can tap into any phone call, email etc. etc. etc. apparently a chinese fellow wants revenge from the organisation so he states that he makes a code which the machine cant break but he is killed by this organisation to get the code but the whole plan back fires. the main characters are a women workin the oraganisation and her boyfriend. the story revolves around trying to obtaining a ring which the chinese guy had worn while he was killed as that is supposed to have the code inscribed on it. the boy friend is sent to get the ring but some one else from the organisation is trying to take him out and te ring for himself. basically in the end the whole goverment data od the usa is at stake in the end, can they save the us goverment secret information from becomin global????? (apoligies to everyone as the review is rlly vague and incomprehensible but then again i had read the book long back)
