There's a reason why Dan Brown is so popular and why people love and hate his books. I have read every book that he has written. Actually not every book, I am yet to complete his latest book the Origin.
And the reason why I enjoy his books is that they are filled with knowledge and each and every thing in the book comes from reality.
He blends the facts into the stories in such a way that you end up gaining so much knowledge that you feel overwhelmed.
The Dan Brown stories are thrillers and there is not a single moment where you would feel bored. And at the end the stories always teach us something.
Something that makes us think and ponder. And that's why I enjoy reading Dan Brown.
