J.K. Rowling's Harry Potter series has sold more than 450 million copies, making her one of the most successful authors in the world. Jo regrets that her mother died before the first Harry Potter novel was published and never knew of her daughter's literary success. Jo reveals that her mother was a quarter French but never had a chance to explore her French roots. Jo is keen to investigate this side of her heritage on her mother's behalf.
