You all know the stats: 90 million books sold, squillions raked in at the box office, a whole lotta fans. But as we come to the 15th anniversary of the first book in the Harry Potter series (...and the Philosopher's Stone), Bloomsbury is on the hunt for the biggest Harry Potter fan in Australia and New Zealand. You could be it – if you can write in Rowling-esque prose. All you have to do is write a letter of no more than 50 words explaining why you lurve these books, drop it off at your local book store and wait. One winner will be chosen from Australia and one from New Zealand and each will receive a leather-bound, signed, dedicated and numbered 15th Anniversary Edition of Harry Potter and the Philosopher's Stone, a Harry Potter Special Edition Boxed Set and a Harry Potter Audio Boxed Set. The competition runs from June 26 to July 31 and for full details on how to enter head to the Bloomsbury website.
