Oh. Um. I'm sorry. Such a long, brilliant, marvellous fic deserves a long, detailed, loving comment. Only I'm a bit ... overwhelmed right now. Overwhelmed in a good way, though. But still at a loss for words for a coherent, long and detailed comment. And just saying "I loved it!" doesn't seem enough. Not after such intensity.
Not that I can think of anything else to say, really. I loved your original characters. Adrian was so adorable. And Odile funny. I wonder how far her manipulations went. And keeping Mrs Black's portrait for entertainment purpose! That one was a very original original character. All of them where very enjoyable, round characters, though, IMO. Kudos for that feat alone.
Also, I really liked your alternate end of the war. The last battle at the Ministry. How Snape pulled the last Horcrux out of Harry. And, yes, of course the relationship between Harry and Snape. I thought it very much in character for Harry that he was so angry with Snape and did all kinds of horrible things to him. He always does things like that, without thinking about them first, and afterwards being angry with himself for doing them in the first place.
Plus, I thought it fascinating to see how little Harry's emotions changed. I mean, how you described them. Whether hatred or love, they were just as intense and fierce. Although, I think I remember moments when Harry's ghosts seemed to reach out for Severus when the two of them were in contact. Sublte hints? Or is that me over-analysing things again? Anyway, I liked that.
And, phew, was the sex hot! *fans self* Harry wasn't the only one kept breathless and wanting.
The end ... how they defeated the fire and Harry surrendered so completely .. *sniffles* That was so heartbreakingly beautiful. Severus's sacrifice of taking Harry's ghosts from him as well. Gah, if that isn't typical of Severus, doing something so nice, for lack of better words, for someone else that only makes himself more miserable. Heh, and then go and snarl at Harry because Harry doesn't do what Severus wants him to do. Typical of them both.
And I kind of like the ending. I like to think that Harry will rebuilt his life and then, in a couple of years perhaps, go and find Severus. Who, by that time, has developed a brilliant potion for ending the ghosts' possession of his soul and body, has become a millionaire and lives in a rose-covered cottage by the sea. Or perhaps not. But me being a sappy romantic I'd like to think that Harry will go and find Severus.
Oh, look at that! I wasn't quite as at a loss for words as I thought ... But I still can't think of anything better to say than "I loved this fic!"
