JK has said no to the title of book 6 being "Harry Potter and the Pillar of Storgé. " Here is what she said:
"I am trying very hard not to feel offended that anyone thought this was possible. 'Storgé', for crying out loud. Come on, people, get a grip."
I have also found out that the new, real, title for the 6th Harry Potter book is behind the now unlocked door on JK's site. Although, when you open it you are just given a brick wall. If you want to figure out the combination of bricks you use to get behind the brick wall, then don't decode this. But, if you are just dying to know the combination, then click here.
I hope you enjoy the new title as much as I do, and can't wait to read the book!
