The photo book seems quite like JKR's writing style, it's just got a terrible plot. There are a number of questions that were supposed to be answered that weren't, and the description of what happens to a secret when the keeper dies in the book is NOT the same as the description Jo gave on her website. There are only two scenarios. 1. This is the real book, and it is terrible. 2. Jo wrote a fake book and allowed it to be leaked to help preserve the privacy of the real book. There is no way the leaked book is fan fiction.

Several days ago, I decided the online jpg book was fake, due to stylistic problems. However after thinking about all the the books, each book was significantly different in style and tone than the one before it, particularly after book 2. So that is probably not enough to prove it is fake. Personally, I thought it was excellent. If fan fiction, far and away the best ever! I will be in line to buy the real book tonight, and won't be really surprised if this online copy is the actual book. I sort of hope it is not though, because each real book has been far better than the best fan fiction.
