Plot Summary: When Harry Potter goes back for his fifth year at Hogwarts, he finds the new Defense Against the Dark Arts teacher, Dolores Umbridge, gradually taking over the school as per the instructions of her real employer, the Ministry of Magic. Meanwhile, his godfather, Sirius Black, introduces him to the Order of the Phoenix, a band of magical rebels dedicated to defeating Voldemort and his followers. In the same spirit, Harry forms Dumbledore's Army among like-minded peers at Hogwarts, banding together to drive out the tyrannical Umbridge after she takes over Dumbledore's position as Headmaster. Harry's involvement in both of these groups, combined with his other problems, push him almost to the breaking point, and although he makes it through his various ordeals, victory will not come without a strong measure of personal tragedy.
