Finally school again... Such a sigh can only be given by those whose holidays were hideous and whose memories of the past school year were wonderful: Harry Potter. But as in the previous year, not only magic potion lessons and transformation are on the agenda. A dreadful thing is going on in the walls of the school - a monster for which no one, not even the most powerful magician, can find an explanation. With the help of his friends Ron and Hermione, will Harry be able to solve the mystery and free Hogwarts from the grip of the dark forces?
