The biggest event of the year for millions of muggles is only one week away.
On the stroke of midnight, 21 June The Order of the Phoenix comes out - as if you need reminding!
And CBBC Newsround's website have found out there will be some strange sights across Britain as the midnight hour approaches.
Watch out for owls!
At the other end of Britain, at Ottakar's in Newport on the Isle of Wight, owls will be greeting Potter fans.
Wonder if Hedwig and Errol will be among them?
Boarding schools like Hogwarts are famous for their midnight feasts and several book shops will be celebrating into the small hours.
Readers will be partying in their pyjamas at Hammicks in Bracknell, where there'll also be readings and fancy dress.
Meanwhile, Borders in Edinburgh is holding a treasure hunt. Wonder if they'll have to find a golden egg, like Harry in the Triwizard tournament?
And down in Cornwall, The Falmouth Bookseller promises to create a totally spooky atmosphere. It's throwing open its doors at midnight, when the shop will be lit by candles.
Padlock
At Borders in Swansea, one lucky reader will get to open the padlock on the first crate of books to arrive there!
And a magician called Billy Bubbles will be entertaining the queue at The Dublin Bookshop in the Irish capital.
Bet Billy could teach Gilderoy Lockhart a trick or two!
Speed readers will be showing off their skills at Books, etc. in Manchester.
Hope they get plenty of rest before the event!
With OOTP being about 768 pages long, they could be there for some time!
(Man...they're going to have a blast!)
