The Order of the Phoenix (Rowling, 2003)

Harry and his friends are growing up. Adult wizards and witches are worried about their safety from the advocates of Voldemort but Harry, Ron and Hermione are enthusiastic to fight against the villains. Members of the Ministry of Magic including the minister Fudge, refuse to listen to Dumbledore’s and Harry’s warnings and do not admit to the resurrection of Voldemort.
Harry is invited to the ancient home of Sirius’ family and notices that Ron’s parents, teachers and his god father have joined the Order of the Phoenix, an association founded by Dumbledore to protect the magical community against the Death Eaters and Voldmort who commit atrocities. The hope of Harry to participate in the Order of the Phoenix is rejected by the adults since he is considered a teenager. When Harry returns to school, many wizards and witches express hostility on the basis of misinformation about the relation between Harry and Cedric’s death and the use of magic in the Muggle world. The Ministry of Magic appoints Dolores Umbridge as the principal of Hogwarts, she is a bureaucratic and hypocritical follower of the law of the Ministry of Magic. The school becomes a boring and painful place for students of Gryffindor because of Umbridge. Moreover, Umbridge forbids students to learn Defense magic against the Dark Arts. Students who disagree with the educational policy of Umbridge and believe they need to seriously learn magic, voluntarily constitute and participate in a secret organization while naming it Dumbledore’s Army. Harry trains his friends in disarming spells. However, Umbridge finds out about Dumbledore’s Army and tries to expel students. Harry and friends get out of the impasse by Hermione’s wit.
Harry and his friends go to the Ministry of Magic to rescue Sirius, thinking that he has been taken by Voldemort. Harry and his friends fight against the evil wizards and witches and members of the Order of the Phoenix come to help them. In the middle of the battle, Harry loses his precious guardian, Sirius. After the battle, Harry and his friend realizes the beginning of the war between good wizards and witches and their evil counterparts.
