I just finished reading this and I think the story is pretty good if it could make me sit and read the whole thing in one go. You have a good style of writing, obviously, but i'd just like to add that maybe you it all happens too fast. Slow it down a little. Also, if you could separate the para's out more its easier to read. Ignore the advice if you want, i mainly commented to let you know this is a good piece of work.
Aw, now I feel bad b/c that was one part of the book I legitimately liked very much (when Harry asks Luna to go with him as friends). But I guess it's ok. After all, Katie seems to be a real sweet type of girl. ^_^
