J.K. Rowling, author of the mega-popular Harry Potter book series, will be making an announcement about Pottermore on June 23.
The one thing we do know about Pottermore is that it's not another book. A representative of Rowling told the Guardian Thursday, "All we can say is that Pottermore is the name of J.K. Rowling's new project. It will be announced soon, and it is not a new book."
If you'd like to count the seconds until the big reveal, you can do so at a special Pottermore-themed YouTube page, which proclaims only, "The owls are gathering. Find out why soon."
There's also a Pottermore Twitter account, which so far holds two updates: one relating to the aforementioned YouTube account and the other to Secret Street View, a Google Maps-powered puzzle game that revealed the letters "POTTERMORE" to Harry Potter superfans who played.
So, keeping in mind this is all idle speculation, what do you think Pottermore could likely be?
