Harry Potter remains at his house, 4 Privet Drive, living with his Muggle aunt, uncle and cousin and severely cut off from the rest of the wizarding world.
The neighbourhood is suffering from an exhausting heat wave and due to this, Harry spends the majority of his summer out of the house, going on walks and trying to avoid his aunt and uncle as much as possible because the paranoid pair won't stop badgering him over his interest in the news.
After running into his cousin, Dudley Dursley and his street gang on a walk, Harry confronts Dudley after his gang leaves which turns into an argument, where Dudley mocks Harry about Cedric's death, having heard Harry use that name in his sleep.
Harry immediately denies it and when Harry takes out his wand and pretends to curse Dudley with it; a cold chill comes onto the duo and Harry and Dudley are then attacked by Dementors.
Harry is in his fifth year at Hogwarts School as the adventures continue. Harry has a lot on his mind for this, his fifth year at Hogwarts: a Defence Against the Dark Arts teacher with a personality like poisoned honey; a big surprise on the Gryffindor Quidditch team; and the looming terror of the Ordinary Wizarding Level exams.
The Weasleys, Hermione Granger, and Harry’s godfather Sirius Black are there.
While the Order of the Phoenix are having a meeting, Mrs Weasley takes Harry to the room where Ron and Hermione are before heading back.
As Harry is explaining that the Dementors are responsible, Petunia surprisingly shows she has some knowledge of the Dementors.
A second letter from the Ministry arrives stating that Dumbledore has convinced them to set up a hearing on 12 August to decide whether or not to break Harry's wand and Harry is being placed on suspension instead of being expelled.
