J.K. Rowling's fifth installment, 'Harry Potter and the Order of the Phoenix,' plunges readers into a darker world. Harry returns to Hogwarts, facing a skeptical Ministry of Magic and an oppressive new Defense Against the Dark Arts teacher, Dolores Umbridge. As the wizarding world denies Voldemort's resurgence, Harry, Ron, and Hermione secretly form Dumbledore's Army to prepare for the inevitable fight. This book explores themes of denial, authoritarianism, and the challenges of leadership, culminating in a devastating loss and a deeper understanding of the prophecy shaping Harry's destiny.
