These Potter fans wanted to be among the first to get their hands on the final book of the most popular book series in the world ever so they started queuing outside a London shop three days before it goes on sale!!
You can't buy Harry Potter and the Deathly Hallows until just after midnight on Friday, but that didn't stop fans travelling from Belgium and the Netherlands to start waiting on Wednesday.
And Potter fever isn't just raging in the UK. These fans are camping out in Helsinki, Finland, to get their copies, which have been closely guarded to try to stop the plot getting out.
Some of the book's secrets might have been leaked, with what look like genuine pages from the book springing up on the Internet. But this is real - it's the first book signed by author JK Rowling outside a New York book shop.
So what happens might be a secret, but that doesn't stop people from guessing! Wonder what this fan, with a BIG poster, thinks will happen? He's in Bangkok in Thailand with the American cover of the book.
The book is expected to fly off the shelves in Cambodia in south east Asia. Hope these two have pre-ordered their book!
JK Rowling wrote the first novel in Edinburgh - where these eager fans are camping out to read about Hogwarts.
Fans queue up for the book launch, which is being attended by author JK Rowling at The Natural History Museum in London.
As soon as the clock struck one minute past midnight, these workers in Tel Aviv in Israel rushed to let fans get their copies of the book as quickly as possible.
Finally fans were getting their hands on the book everyone's been waiting for.
