I just finished reading up to this point - your story is crazyfun. I love the whole concept of Luna going after a husband and inadvertantly saving Harry Potter. I love how they're just doing what they want and saving the day.
Dumbledore, however, is irritating me. I can't really pinpoint why, as he is just as intentionally OOC as everyone else, and no one else bothers me. I guess that I just have a hard time accepting a completely clueless Dumbles. But that's really more my problem than yours.
I like how the story is unfolding and Iook forward to reading more.
