J.K Rowling - Harry Potter

The adventures of a certain boy wizard were enough to propel J.K Rowling into millionaire status but by 2007 the story that began it all came to an end. Rowling said goodbye to the series with the launch of the seventh book, Harry Potter and the Deathly Hallows. The idea for the series was born on a long train journey and by the time the author disembarked she couldn't wait to start writing. Seventeen years, seven books and six movies later, the author says she'll be sad to let go of Harry, but admits it's time to move on.
