Query: Weak on facts, very far fetched

This book is moderately well written; it has no serious continuity gaps but has a lot of fiction and not enough truth to intertwine with to make a decent pseudo-scientific fiction.Dan Brown lacks the power of a good storyteller to make his readers belive his "facts", and also, his supposed riddles are weak and an insult to try to make us belive that an educated mind would have trouble solving them, much less, survive the ages without anyone being the wiser.A good read for anyone interested in "hardy-boys" type of books.
