From the summary it looks like you've been inspired by Miranda Fairgold's work.
I have never been a big fan of stories that introduce a bunch of non-canon creatures and then proceed to make them the centerpieces of the work. I hope you don't go that way. :)
Still, this looks interesting, and I'll keep watching...
Author's response
Yeah, I've read hers and a few others, so doubtless they'll have somewhat of an impact on this story. Unlike that story however, mine won't be focusing nearly as much time on Harry actually in school. Thanks for the review.
