Oh my goodness. Wow. Oh just wow. I know that you wrote this a while ago but it's new to me and I have to stop and comment on the absolute brilliance of this story. I admit that I was a little freaked out by how much your Harry reminded me of well, me and IMO when a piece of fiction is so well written that you can learn something about yourself from it, that's special.
Personal affinity to the characters aside this has so much going for it. First of all that was insanely creative; I've never read "How to be Good" but this fit Harry and Draco so well, it works in a way I couldn't imagine. Next credit has to go to your balance, the plot and the characters themselves are this wonderful mix of broken, crazy, endearing, creepy, funny, desperate, REALness! And speaking of characters how you fit them all into this story while keeping them so true to form was great. I also loved your details like cadence of Ron and Harry's relationship and the fact that apparations are contributing to global warming, IDK there was just so much win! I'm going to bookmark this one an I known that I will read it again and again, but first I have to go check out your master fic list!
