Hmm okay, i wasn't sure at first but i can see the story building upa to something. A bit of advice? I think you need to work on Stokley. She's a good character, but doesn't seem to be strong enough yet (by that i mean well-developed). Are you comfortable with her as a character?
I also feel your Draco and Pansy are a bit too far OOC - but its your story and it is fanfic so do your thing.
Grammatically speaking - do you have a Beta? You should probably get someone to check over your story and give you some tips.
But i like what you have come up with so far, so keep posting.
