Harry Potter and the Order of the Pheonix

The fifth installment in the Harry Potter series follows Harry's turbulent fifth year at Hogwarts. Facing disbelief about Voldemort's return, a corrupt Ministry of Magic, and the tyrannical new teacher Dolores Umbridge, Harry forms Dumbledore's Army to teach defensive magic. The story explores themes of rebellion, grief, and the burden of prophecy, culminating in a devastating battle at the Department of Mysteries. Darker in tone than previous books, it marks Harry's transition into adolescence.
