Harry Potter and the Order of the Phoenix is the fifth and antepenultimate novel in the Harry Potter series written by J. K. Rowling. The novel features Harry Potter's struggles through his fifth year at Hogwarts School of Witchcraft and Wizardry, including the surreptitious return of Harry's nemesis Lord Voldemort, O.W.L. exams, and an obstructive Ministry of Magic.
It is the longest book in the series, and was published by Bloomsbury in the United Kingdom, Scholastic in the United States, and Raincoast in Canada. The book has been made into a film, which was released in 2007, and has also been made into several video games by Electronic Arts. Harry Potter and the Order of the Phoenix has won several awards, including being named an American Library Association Best Book for Young Adults in 2003.
The novel was also received generally well by critics. Rowling was praised for her imagination by such reviewers as USA Today writer Deirdre Donahue. Most of the negative reviewers were concerned with the violence contained in the novel and with morality issues occurring throughout the book. There has also been a strong religious response to the publishing of Harry Potter and the Order of the Phoenix.
