Do you know any books as interesting as Dan Brown's books?

If you are looking for FACTS I suggest novels of Jules Verne.They have a lot of details and descriptions on geology.Journey to the Centre of the earth,Twenty thousand Leagues Under The Sea,Around the world in 80 Days etc. by him are all time bestsellers.Willard price is another writer of the same kind.The other two novels of Dan Brown,Deception Point & Digital Fortress, are adventure+fact packed.Sherlock Holmes novels by Sir Arthur Conan Doyle introduces readers to a new science, umption through observation.They are really interesting!!
