I'm hoping someone can help - I was reading a fic when, joy of joys, Firefox glitched. Now I can't recall the title, can't seem to find it with a search, and my browser history's no help. It was an "I dressed as Harry Dresden" fic, but the part that comes most vividly to mind is that, in the last chapter I recall reading, MAB shows up in Equestria, pissed that someone is wearing the face of HER Winter Knight.

Can anyone help?

Sorry, I put the wrong link... I think its this one though. Can't seem to recall it that well.
