JK Rowling has finally spilled the beans on her new Potter project - called Pottermore - and Ricky was there to hear all about.
Over to you Ricky...
"For weeks Potter fans have been tinkering away online trying to crack a mysterious code.
As if by magic, a website popped out of nowhere called Pottermore and JK Rowling told her fans that something big was on the way.
Well, after spending the morning with JK at a top secret launch event I can tell you that Pottermore is a website featuring brand new material written by the famous author as a way of saying thanks to her fans.
The site launches on Harry Potter's birthday, 31 July.
The website includes 18,000 new words by JK Rowling, including biographies and extra nuggets of information, like her inspiration behind Privet Drive and even the back stories to some of Harry's teachers and friends.
JK Rowling looks at the site with Simram and Ivy, both 12
There are loads of new illustrations and even a series of questions which will determine which house you should be in at Hogwarts. (Fingers crossed you get Gryffindor and NOT Slytherin!)
The site also takes you on a journey through each Potter book, where you can collect coins to spend in Diagon Alley. You can also mix up your own virtual potions and upload pictures and comments.
When Pottermore launches, the content will complement the very first Potter book - The Philosopher's Stone.
Then, over the next couple of years, the website will grow and more will be added. JK said she's been storing all this extra magic for nearly 15 years!!
For fans desperately clinging onto the hope of a new book, I'm sorry to say I've got bad news
there won't be one! However, JK Rowling still has plans to write a Harry Potter encyclopaedia, with all the proceeds going to charity.
More girls try out the website
The website is free to use, but you will have to spend a bit of cash if you want to download the digital copies of the books.
I can't wait to have a proper nosey around the site when it officially launches. Judging by what I saw today, Pottermore looks like it will entertain fans for hours.
But there was a small part of me expecting a bigger announcement, something a bit more exciting
I still live in hope that a new book might one day arrive in the Newsround office. Keep dreaming Ricky
