For me, the Battle of Hogwart's last duel was a bit inadequate. I mean after reading so many fan-fics where there is a lot of action, this one-spell ending was a bit short and disappointing. If you've read DK's DOP, you'll know what I mean.
There is also one thing that is nagging at the back of my mind--- Does J.K read the fan-fics??? I think she does....Here's the evidence....
I am following a fan-fic called the Harry Potter and the Amulet of time where Harry, Ron, Hermione and Ginny find themselves back at the time of the Founders (Book1) due to an amulet which Harry got on his B'Day from Hermione.
There, Harry falls in love with Rowena Ravelclaw's daughter. Gallatea Rawenclaw bounds her soul to the Hogwarts grounds for Harry to free her when he returns to his own time. After he frees her, she joins the other ghosts and takes her position as the GREY LADY---Ravenclaw ghost!!!
Any similarities in the last book with this one??? Mind you, this fan-fic was written after Goblet and doesn't have Order of Phoenix in it for most of the first book.
