It’s been nine years since the last book in the Harry Potter series was released.

And its final chapter – Nineteen Years Later – gave us a glimpse into the future lives of Harry, Ron and Hermione as fully formed adults and parents.

At the time fans saw it as a teaser into their favourite characters future lives – giving us just enough information to carry on the story in our imaginations.

But now finally we have the next chapter of the story with Harry Potter and The Cursed Child - only this time it’s a two-part play rather than a book.

The script goes on sale at midnight and Waterstones in Bournemouth Arcade is throwing a very special wizarding themed party from 11pm before the script is finally released to the world.

Many of the hundreds of thousands of people who have tickets to the play at the Palace Theatre in London haven’t actually seen it yet so there is some trepidation about whether to read the script beforehand.

There’s also that age old question about whether scripts should be read?

So without releasing any spoilers here’s what we know about the latest instalment of the Harry Potter universe.

1. The play, written by Jack Thorne, is set 19 years after the seventh and final book in the series by JK Rowling

2. It’s presented in two parts and runs to more than five hours

3. It will see the return of some of our favourite characters (the ones that didn’t die in the Battle of Hogwarts) as well as their own children who are now heading off to Hogwarts

4. The play has been showing at London's Palace Theatre since June, but officially opens today

5. There were real owls in the performance originally but after an incident where they got loose they have now been replaced for fake ones

6. There is, of course, magic: flying books, a wand fight, and even some dementors that float out over the audience.

7. Part 1 ends on a big cliffhanger.

8. The play is about Harry and his three children – but especially his son Albus Here is a snippet from the play’s blurb: "It was always difficult being Harry Potter and it isn't much easier now that he is an overworked employee of the Ministry of Magic, a husband and father of three school-age children. While Harry grapples with a past that refuses to stay where it belongs, his youngest son Albus must struggle with the weight of a family legacy he never wanted. As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes, darkness comes from unexpected places."

9. Although tickets for the play sold out pretty quickly 250,000 extra tickets go on sale on Thursday, August 4 – to get yours go to harrypottertheplay.com

And just a friendly warning if you do buy the script don’t forget to "keep the secrets" to avoid resentment and anger from other Harry Potter fans and creator JK Rowling.
