The whole set up for this story -- the idea that Hogwarts chooses/approves/accepts her Headmaster, that she mourns the death of McGonagall, that the castle could be exorcised -- is just so damn cool. But really, what I think I like most about this fic is your Harry. He's not an idiot and he's not a kid. She's a sharp, in control (mostly!) adult. He's someone who could hold authority and be a real match for Snape. Everyone putting Lucius in his place was just an added bonus. >:)
