I read it a long ago. After knowing it was not written by J.K. Rowling, I was a bit unhappy. A writing of this caliber should not go unnoticed. Truly, it almost fooled me into believing that I was indeed reading the last book in the Harry Potter series. Then the real 7th HP book came and I forgot all about this fanfic. Recently, I remembered and searched for it again. (I've found it! :) )I will definitely re-read it and try to give a review.
You can find the fanfiction here: (And such a great fanfiction, too. :D )
