You've still not given a lot to go on for a fair vote. The story is a bit light still, although i realise it's hard to give people a good idea of what you're thinking if you haven't started it yet. Get paper+pen and start working up a mindmp or something. Get a better idea yourself and then update this. You should get more response if theres more to respond to, although for what it's worth, the story sounds interesting, but possibly a bit too reminiscent of Potter..unless you've just....not written a full account of what yo're thinkin' so far....
