Harry is no longer a boy. At 15, he continues to suffer rejection from the Dursleys, his strange family in the 'Muggles' world. He also continues to rely on Ron Weasley and Hermione Granger, his best friends at Hogwarts, to carry out his investigations and adventures. But the little wizard begins to feel and discover new things, such as first love and sexuality.
In previous volumes, JK Rowling has shown how Harry was made a celebrity in the world of magic for defeating, as a baby, Voldemort, the all-powerful dark wizard who murdered his parents. In this fifth book of the saga, the protagonist, in a typical teenage crisis, has attacks of bad temper with the persecution of the press, which follows him everywhere and even invents statements he never made.
Harry will face Voldemort's onslaught without Dumbledore's protection, as the headmaster of Hogwarts is removed from the school. And it will be without the help of his protector that the young hero will face discoveries about the controversial personality of his father, James Potter, and the death of someone very close.
