I am one incredibly happy (if a bit sniffly) Snarry fan. To now have a such an amazing story that includes my third favorite HP character - Luna - to read and reread, is a wonderful thing. :)
And what a perfect Luna! You've written the one that lives in my head. Eccentric, full of life, but oh so intelligent. I'm so glad she finally got to where she was going, even if where that was caught me quite off guard. The ending, with its twist...guh.
Major brownie points to you for incorporating the theme of "Back to Hogwarts" in a way no other writer had done up to now. Mid-way through the story I was really wondering and when it was apparent how you were weaving it in, I really was amazed at your brilliance. Well done.
I can't begin to tell you how much I loved this. Only that I will definitely reread it about a gazillion times. Proof enough?
