New short stories revealing the intricate details of the life of seven Harry Potter characters are coming.

J.K. Rowling has written three new collections of short stories which will take a deeper look at the dark side of the wizarding world. Available only in ebook, the collections will be available next month. Curated and released by Rowling’s interactive Pottermore website, the collections will dive into the backstories of Remus Lupin, Minerva McGonagall and Dolores Umbridge.

“Power, Politics, And Pesky Poltergeists” will take a look at Umbridge’s ruthless rise to power and provide a look at the relationship between Professor Horace Slughorn and young Voldemort during his time at Hogwarts. The short stories will further Slughorn’s backstory with Tom Riddle, as touched upon in “Harry Potter And The Half-Blood Prince”.

The new short stories come after Rowling announced that “Harry Potter And The Cursed Child” would be the eighth and final book in the Potter saga.
