If you recall, JK Rowling wrote a prequel to the Harry Potter series that was auctioned off today and sold for £25,000 ($48,855 U.S.)

J.K. Rowling’s handwritten prequel to the “Harry Potter” novels fetched 25,000 pounds ($48,855) at a charity auction in London tonight. The signed, 800-word tale was one of 13 “storycards” written on sheets of A5 paper being offered by Waterstone’s, a U.K. bookseller. The signed piece concludes with the teasing words “from the prequel I am not working on — but that was fun!”

Fans will be able to read the prequel online tomorrow (June 11th) on Waterstone’s  official site
