This time, everything goes so wrong during the holidays that Harry fears he might get expelled from Hogwarts for using a levitation spell to send his unbearable Muggle aunt Magda to the ceiling and then simply running away. While he is still imagining a life as an exile, the Ministry of Magic catches him, and to his own astonishment, he arrives back at the castle just in time for the start of school. But now the real trouble begins! Why is a feared criminal hiding in the castle? How did he even manage to get in? And why is he after Harry? It seems that Harry's situation is much more complicated than anyone wants him to believe. Together with his friends Ron and Hermione, he tries to unravel a web of betrayal, revenge, slander, and cowardice, stumbling upon incredible things along the way.
