Surely, somewhere, at the Hogwarts School of Witchcraft and Wizardry, lies a dusty, never-before noticed spell book. In that book, J.K. Rowling, the celebrated creator of Harry Potter, could find the formula that would transform her into a critically acclaimed writer of adult fiction. But Rowling isn't relying on magic as the release date for her adult novel, The Casual Vacancy, draws near. She believes her reputation for creating great characters and compelling stories will trump any spell that Harry or his mentor, the all-powerful Professor Dumbledore, could ever conjure.
