Hi-
I haven't reviewed this yet, but wanted to let you know that I'm enjoying this immensely.
Considering that the genre of "Harry time travels to the MWPP era" is hardly an new territory, you've done a really nice job here.
(Here's my constructive review, please take it in the spirit in which it was intended). Looking at your body of work as a whole, I think that I best enjoy your stories where Harry isn't explicitly paired with either Hermione or Luna ("Scenes From October" is probably my fave, I also really enjoyed "Six Virgins")... not that I don't enjoy the other stories, but I've noticed that when you pair Harry with Hermione or Luna you fall into some familiar patterns and skip a lot of the development of the relationship.
In this case you've created all of the relationships from scratch and I think the story is better for it.
Anyway, hopefully this is helpful; if not, I was drinking when I wrote this :)
