J.K. Rowling has already written a follow-up to Harry Potter and the Deathly Hallows, the last in the Potter series, but you're never going to read it. That is, unless you are someone very, very high up the food chain at Amazon, who purchased one of seven copies of the book, The Tales of Beedle the Bard at auction for a whopping 1.9 million British pounds, or just over $3.9 million dollars.
The book, which is alluded to in the Potter series, is a handwritten tome of wizard cautionary tales, written and illustrated by Rowling herself. All of the proceeds from the auction will go to a charity she helped establish known as The Childrens Voice campaign, which helps provide a better life for institutionalized children. How lovely of her.
