J.K. Rowling published Harry Potter and the Goblet of Fire in 2000.
The fourth Harry Potter novel was released in the United Kingdom on 8 July 2000 and in the United States on 8 July 2000 under the same title. It expands the series beyond Hogwarts through the Triwizard Tournament, an international magical competition held during Harry’s fourth school year.
Harry is unexpectedly entered into the tournament despite being under the required age. The contestants complete dangerous tasks involving dragons, a lake rescue, and a maze. The book ends with the return of Lord Voldemort, marking a major shift toward the darker final part of the series.
Goblet of Fire was notably longer than the earlier novels and became the first Harry Potter book to be published simultaneously in Britain and the United States. The film adaptation, released in 2005, starred Daniel Radcliffe as Harry.
