Dawn at Hogwarts? I don't remember if I've read that one or not, but I'm game to read it if you decide to continue it. :) I enjoyed the Potter books up until Half Blood Prince, then I decided I would see what direction they took for the last book and never bothered to read Deathly Hallows. The Prisoner of Azkaban is definitely my favorite of the books and I much prefer to read Harry Potter crossovers when it comes to the fan fiction.
