J.K. Rowling is publishing two new Harry Potter books with 'hidden details'

The good news just keeps on coming for Harry Potter fans after it was confirmed that J.K. Rowling would publish two more books.

Ahead of the eagerly-anticipated first series of the television adaptation, which is set to release in December, fans will be delighted to hear about two new books from the esteemed author, which promise 'new details' about some of the most beloved characters from the wizarding world.

Bloomsbury Publishing is expanding its collection of 'Pocket Potters', which are short stories about the magic of our favourite faces from Hogwarts that are aimed at children.

However, Harry Potter lovers of all ages can still get a kick out of reading the mini-books, as they are brimming with enticing tales, quotes, illustrations and facts.

After some releases earlier this year - delving into the adventures of the likes of Rubeus Hagrid, Dobby and Professor Dumbledore - the two new books will be centred on three of Harry's closest allies.

Professor Minerva McGonagall, and the Weasley twins, Fred and George, will take centre stage in the new Pocket Potters.

Previous editions have explored the escapades of beloved characters such as Harry himself, Ron Weasley, Hermione Granger, Professor Dumbledore, and Luna Lovegood.

Fans of the films and the books typically love any magical merchandise that is related to Harry Potter, so these books will likely be no different - especially for those raising a new generation of Potterheads.

Bloomsbury Publishing writes: "Lifelong fans, too, will love revisiting the wizarding world through wonderfully drawn pages, spotting the many hidden details and Easter eggs, and remembering the moments where the magic all began."

It also suggests that fans will get the answers to questions such as: "Why does Professor McGonagall buy Harry Potter a broomstick? Which animal can she transform into and what is a Hatstall? Can anyone tell Weasley twins Fred and George apart? How do they know every secret passage in Hogwarts, and what is a Canary Cream?"

So, if you can't wait for the second season comes out to get some more coverage of the wizarding world, then you can pre-order some of the new 'Pocket Potters' online now.

Otherwise, you can hang on until 23 February next year, which is when the mini books about McGonagall and the Weasley twins are set to hit the shelves.

These are hardcovers which are 32-pages long, just like the rest of the Pocket Potters book series, and are expected to set you back around £10.
