The Telegraph is reporting about how well the Harry Potter prequel JK Rowling wrote is selling! It became the fastest-selling short story of all time when the entire print run was snapped up in a single day. ‘ Ordinary fans got their chance to own a copy when 10,000 cards went on sale at Waterstone’s branches across the country. Such was the demand that many stores had sold out by lunchtime, and all 10,000 copies were gone by close of business.’

Thanks DC!
