The Wizard Behind Harry Potter a try.
Sadly things were not what I thought they would be at all. Mainly it consisted of quotes Mrs. Rowling made during interviews and what seemed like a lot of assumptions to fill in the gaps. Since Mrs. Rowling was not involved in the book I find it hard to believe the Marc Shapiro knew what she was thinking. If I ever try another story of Mrs. Rowlings life it will have to be in the autobiographies category.
