It's not a book, we know that much. Scholastic told Entertainment Weekly as much. But Harry Potter author J.K. Rowling has something in the works, and all will be made clear in a little less than a week if this countdown clock is to be believed.
All of this started with a viral campaign in which a set of coordinates were given to 10 Potter fansites. Each string of numbers pointed to a letter on a Google Maps site, eventually spelling out "POTTERMORE." Which led to the revelation of a new website, Pottermore.com, with a simple design and a promise: Coming soon. There are a lot of theories flying around out there, and I've got a few of my own. I'd rather hear what you all think, though.
