I'm so glad that i found this story again, i thought that i had it so ficwad would email me with updates, but apparently not.
I would actually prefer for you to not include a snape/lilly dynamic. I found it to be really...obsessive on JKR's part. To me the fact that snape could not be a complete bastard and still do the right thing because it was right...i found it really ridiculous that he did it for a woman who he was friends with at 15.
I would like to see more interaction with Harry and James and Lilly. I like the progress and changes that Harry is causing within the student body.
Why did Ginny not die in second year if she still has the diary...and if Tom has a body..why is his diary self not trying to merge with it??
I just find 4 years of being posessed a bit of a stretch.
Oh, whats the deal with Narcissa's youth potion? This story brings up many interesting questions and thoughts, i hope you give us an update soon.
