Well, I've read all the books and my birthday is on the same day as HP (and his creator), but that's about it. Good books, very readable, craps all over anything Dan Brown wrote.
J.K Rowling's manuscript for Harry Potter was rejected by twelve publishers (i.e Penguin, Transworld and HarperCollins, and etc..) before ever being accepted for publication. Some companies said they didn't feel like it would ever be successful ...... Don't they feel stupid?
