Harry Potter author JK Rowling has announced the release of four new books in the wizardry series.
The new e-books are non-fiction and based on all things from the wizarding world.
Rowling made the announcement via her Pottermore website and said in a statement they had been inspired by a British Library exhibition Harry Potter: A History of Magic.
The series is called Harry Potter: A Journey Through and is based on lessons taught at Hogwarts.
"Prepare to delve deeper into the rich history of magic (be it our own Muggle history, or the magical world created by JK Rowling) with this new series of eBook shorts," said a statement on the Pottermore site.
The first e-book will be released on June 27 and the first two books will explore Defence Against the Dark Arts and Potions and Herbology.
