Amazing start with this (don't worry, I plan on reading the other parts, but I wanted to go ahead an comment now while this was fresh in my mind). I stumbled upon this, and I'm so glad I did! Aside from a few minor grammatical errors, this is really fantastic. You kept Dumbledore very IC, which is extremely hard to do, so props for that. Your writing style in general is great, and I loved the beginning of this... it completely drew me in.
Well, I suppose I'll keep reading now. Just wanted to share my thoughts! Rock on!
