1st I am not JKR, what you recognize as hers, is hers. The first chapter came to me in a dream 47 days before I publish this. I wrote it down, put it in the edit software and promptly forgot it. I rediscovered it today and decided that we will all go on this ride together. It is a slice of the future based on my supposition from the comments JKR has made.
