Dan Brown. Sorry Dan, but you clearly don't know much about any of the subjects your books cover. The research on Digital Fortress for example, is painfully thin and shows glaringly through. Terminology is wrong, logic misapplied. The characters are usually unbelieveably stupid given their supposed status as genius cryptographers and the like. Or, as often happens in Da Vinci Code, the characters unrealistically crack the "impossible" code instantly, revealing the secret a paragraph later, leaving the reader no time to ponder it on their own, as if Brown delivers the punchline to a joke without a pause - the sign of an amateur. Really not feasable, predictable and trite. Good for grocery store shelf paperbacks.
Not going to go into a drawn-out argument, but these books are found in the fiction section for a reason. They're entertaining reads and exciting stories.
