Harry Potter returns to his fifth year at Hogwarts. No one believes his story about Voldemort's return and Cedric Diggory's death. To make matters worse, the new Defense Against the Dark Arts teacher, Dolores Umbridge, is the most horrible, awful teacher they've met. Apparently, the Ministry has put her there to spy on Hogwarts and stop people from believing Voldemort is back. Harry has strange dreams of locked doors and very long hallways. What could it all mean?
