Harry Potter & the Prisoner of Azkaban

What would Hogwartz be like if Dumbledore's daughter was there? It would probably be the most exciting, romantic, and drama filled couple of years at Hogwartz yet!! Elle Dumbledore is absolutely gorgeous and Harry can't help himself from her, but slowly secret after secret is revealed and half of which would change Harry's life forever but still leave a long lingering question to be answered.. Who is Elle Dumbledore?
