I tried to post this comment when I finished this story at 3am this morning but my lovely dial-up access was being a bitch but I just had to come back to comment this morning.
I loved this! Have no idea what the Dresden Files are that everyone keeping talking about in the comments but you really made this story interesting, lots of twists and lots of fun. It was also interesting to have all of the magical community be the same (as far as I could tell) but have Draco be a Muggle. I enjoyed the AU aspects of his character a lot.
Can't wait for the big reveal to find out who you are so I can read more of your stuff!
