Query: Come On !!!

If I were Dan Brown, I would covertly buy all copies of Digital Fortress and burn them at my back yard. Digital Fortress is one of the worst techno-thriller books I've ever read. In fact I was so disappointed with this book, that I simply left it in the drawer of my London hotel - maybe someone else would enjoy it (although I highly doubt it).I don't think Dan Brown is a very bad writer. I read Deception Point (a classic airport novel - good pace, interesting twists, passable science) and I'm half way through the Da Vinci Code. But Digital Fortress is completely off the mark. I've managed to guess each and every plot turn, the "riddles" are simply bad, and even when remembering that the book was published in 1998, the encryption and web technology covered in the book is laughable and lacks the minimum amount of vision you would expect from a techno writer.In short - don't waste your time here.
