This picks up in the middle of HBP, with a few twists, and tells the story as it might have been if Ginny was a little more involved...Don't want to give anything away in the summary for those who haven't read book 6 yet. Please review if you read, criticisms are welcome of course! And it will get more D/G oriented as it goes on, I want to stay in canon as much as possible, so the going is slow.
