His new Defense Against the Dark Arts teacher, Dolores Umbridge, makes Harry and his friends suspicious when her substandard teaching methods and cruel practices come into question. To Harry's despair, she is given the position of High Inquisitor of Hogwarts. Harry, Hermione, and Ron band together to form the D.A. known as Dumbledore's Army. They secretly teach defence spells to protect themselves and the school against the evil that awaits.
Harry Potter and Dumbledore try to warn the wizard authorities that Lord Voldemort will return. Still, they are not taken seriously, and the situation becomes ever more desperate as the authorities work against them, and Voldemort and the death eaters grow stronger and ever more powerful.
