Why everyone reading real books?
Try some Jack Reacher novels or Terry Pratchett books.
I do like Terry Pratchett, but I made the mistake of taking a Jack Reacher novel - a moment of weakness; I'd forgotten to bring a book, stopped off at a charity shop, and thought I'd give it a go - to Bisley with me the other week... dear God, that was awful.
As awful as a Dan Brown book?
Probably in the same league. I ended up reading The Da Vinci Code to see what the fuss was about, finding it predictably bad, and in another display of foolish trust decided to read Deception Point to give the man a fair hearing, before realising that sometimes fairness comes at a price.
