Okay, so here’s one Harry Potter installment that we won’t be seeing on the big screen, but it’s worth a mention. J.K. Rowling has written a Harry Potter prequel — for charity. On a a card slightly bigger than a postcard.

The Harry Potter prequel is a short 800 words long, but oh to know what lies in those 800 words, right?

J.K. Rowling’s Harry Potter prequel will not be published, but rather sold at a charity auction.

Thirteen authors were asked to create a story for the auction — and the only part we know for sure? J.K. Rowling’s note at the end, saying, “From the prequel I am not working on – but that was fun!”
