I loved this story back when I saw it on 3-or-4-part-harmony. I was saddened that it was apparently abandoned. I'm no longer active on that group (and haven't really been since the first year due to lack of time. Heck, I'm not active on CaerAzkaban either), so I'm glad this was posted some place where I can get alerts. I'm disappointed that there was no new material, but at least it's easier to find.
I found the story to be excellent, and it was shaping up to be one of my favorite HP lemons (not that I read that many these days). I hope you do pick it up again some time.
