Here via luvscharlie, but unlike her, I adore Snape, so if she thinks this is good, it must be.

And it is. Luna is the hardest character to write in fanfic, and very few do. You, though, have written her magnificently. She is not an eccentric character, but a holy fool, and they are the wisest among us. She and Snape are the 2 most interesting characters in all of canon, and this story captures them beautifully.

Well done!
