Gah! Where's the other 12 chapters? heh. I loved it, but also agree with the other comment that it ended way before I was ready to let it go. :)
Harry's frustration was so painful. You did such a great job of showing how tough it was for the people around him too, but my heart went out to Harry. I can't even begin to imagine what living without a language would be like. I also like the parallel you drew between Snape and Harry. Both of them half-trapped until their personal demons had been dealt with and conquered. I'm wondering if they ever got the life they expected, or if they were content to start a new life together with a different set of rules?
Well done - even if you are on that other team. :D
