I love how you portrayed Harry as cherrily evil. Great story!
I thought that your name sounded familiar. You wrote "Flames of Betrayal" didn't you. It was a favorite of mine for quite a while and then it just up and vanished from fanfiction.net. If you have your story up elsewhere I'd love to know where so I could reread it.
One thing that I really enjoy about fanfiction is when an author takes the characters that we all know and makes them dance in a way that they normally wouldn't. I enjoyed the way that you did so here.
While there were a few minor typos, it was nothing major at all. The biggest disappointment for me was that this was just a one-shot. I would love to see you turn this idea into a chaptered story, as I think it could be marvelous (nudge,nudge)
Thanks for sharing this with us.
