very nice. You've taken an oft-used genre (dimension/time travel) and made something new out of it. I like what you've done so far, and I can't wait to see how H deals with this world's Posessed!Ginny. I also like the bit with Narcissa. I keep wondering what her plan is. After all, she was a Slytherin too. ;)
Glad to see you're still working on this one (or at least you were as of April). This one's been added to my favs as well as my alert list. :)
