Hey I read your story. First of all I love AU hp stories, got tired of canon like stories years ago! Also this story is well written and has a very interesting plot! Love the whole slave/harem angle. I will admit though I'm a little thrown off by his tail and having to go barefoot! I usually dont like stories where he has a tail, but then again I remember when I first read a story where he had wings I didnt like that one either but now I make a point in looking for stories with him having wings, so I cant really say anything about him having a tail!
I'll definitely be looking out for the next update!
