These stories of power, politics and pesky poltergeists give you a glimpse into the darker side of the wizarding world, revealing the ruthless roots of Professor Umbridge, the lowdown on the Ministers for Magic and the history of the wizarding prison Azkaban. You will also delve deeper into Horace Slughorn’s early years as Potions master at Hogwarts – and his acquaintance with one Tom Marvolo Riddle.

These stories of heroism, hardship and dangerous hobbies profile two of the Harry Potter stories’ most courageous and iconic characters: Minerva McGonagall and Remus Lupin. J.K. Rowling also gives us a peek behind the closed curtains of Sybill Trelawney’s life, and you’ll encounter the reckless, magical-beast-loving Silvanus Kettleburn along the way.
