OMG!!! Write more!!! I've never even read a fanfic till I read yours....and I must say, I am impressed!!!! Brilliant!!!
The only criticism I have is this: when is this all taking place? their 7th year? if so, Karkaroff's dead already.....if not, then when? b/c if it's before their 7th year, wouldn't they all still have The Trace on them? Regardless, it's awesome and Draco's dialogue is highly accurate.
