The book isn't even out until the end of this month, and all of the supposed leaks are nothing more then a bunch of fan crap made up by people with too much time on their hands.
So how did this information get leaked, or is it easy to say it is possible this is also nonsense?
It is 100% FAKE. Unless we have been lied to, the main deciding fact is that this version of the book is 30 pages short of the 784 that the book has been announced to be. The writing style differs at times with JKR's, but I could honestly throw that to the fact the books themselves changed style as they have progressed. The problem I had accepting this as a fake, was that someone obviously took extreme care to disguise it as a real.
While I remain slightly skeptical about it being fake(It just took way too much effort to disguise it as real. I hate to believe someone would purposely try so hard to fool someone), it is one of the best fan fiction work's I have ever read.
Well today on the radio Paul Harvey made a comment that the Author of the last Harry Potter books urged all of the people who got a book early not to divulge any spoilers of the book.
That being said it is most certinally possible that any spoilers you read could be true, but honestly, if I was her, I would only trust my closest friends with the books, people I know who would leak any info.
I heard one story about a mirror being hosted on a website too and that was hacked, but I didn't really believe it, nor did I look it up. But, it's possible a couple got grabbed while they were manufacturing them. I don't really think too much can be done about that, though. (Same thing most likely happens with albums, if they don't get it through a leak, someone gets it once they start manufacturing them)
edit: Turns out people have even got the books shipped to them week(s?) early
It's real, unless there is an awesome fan-fiction writer who printed out a legit looking copy of the book. Then had the publisher get a subpoena for Gaia Interactive Inc to find out the details of where the leak started (Hint: Not there)
If it turns out it's fake, I want to find the author of it and give them money. I'm up to chapter 10 and have loved every bit so far. It's real, something fake wouldn't get this sort of attention from the publisher. Of course they are going to play it down. They spent a bunch on security for the book, they'd look stupid if it was leaked.
