Ack, I meant to *actually* come back and continue the comment when I'd acheived more awakeness units, but that obviously didn't happen. :P I'll have to do it now.
It was the mood of the story, I think, that did it for me; all the family cheer and sexual tension and Harry just sort of muddling through it all. I loved the Harry/Ginny dynamic; they're my anti OTP so I always love realistic depictions of them falling apart, and this was that, very much so. <3 Then the continuation of Ron's - completely canon! - crush on Viktor Krum was so beautifully executed, and I loved how Harry got him first and Ron ended up jealous. Basically, just everything about this fic was awesome :) And the whole thing was sexy as hell. You've definitely earned yourself a new fangirl!!
