J.K. Rowling is the author of the enduringly popular Harry Potter series, as well as several stand-alone novels and a bestselling crime fiction series. After the idea for Harry Potter came to her on a delayed train journey in 1990, she plotted out and started writing the series of seven books and the first, Harry Potter and the Philosopher’s Stone, was published in the UK in 1997. The series took another ten years to complete, concluding in 2007 with the publication of Harry Potter and the Deathly Hallows. Smash hit movie adaptations followed. The Harry Potter books have now sold over 600 million copies worldwide in 85 languages and been listened to as audiobooks for over one billion hours. To accompany the series, J.K. Rowling wrote three short companion volumes for charity: Quidditch Through the Ages and Fantastic Beasts and Where to Find Them, in aid of Comic Relief and Lumos, and The Tales of Beedle the Bard, in aid of Lumos. Fantastic Beasts and Where to Find Them went on to inspire a new series of films
