Harry Potter and the Deathly Hallows is the seventh and final of the Harry Potter novels written by British author J. K. Rowling. The book was released on 21 July 2007 by Bloomsbury Publishing in the United Kingdom, in the United States by Scholastic, and in Canada by Raincoast Books, ending the series that began in 1997 with the publication of Harry Potter and the Philosopher's Stone. The novel chronicles the events directly following Harry Potter and the Half-Blood Prince (2005), and the final confrontation between the wizards Harry Potter and Lord Voldemort.
Rowling finished writing Harry Potter and the Deathly Hallows in January 2007. Before its release, Bloomsbury reportedly spent GB£10 million to keep the book's contents safe before its release date. American publisher Arthur Levine refused any copies of the novel to be released in advance for press review, although two reviews were submitted early. Shortly before release, photos of all 759 pages of the U.S. edition were leaked and transcribed, leading Scholastic to look for the source that had leaked it.
Released globally in 93 countries, Deathly Hallows broke sales records as the fastest-selling book ever. It sold 15 million copies in the first 24 hours following its release, including more than 11 million in the U.S. and UK alone. The previous record, 9 million in its first day, had been held by Harry Potter and the Half-Blood Prince. The novel has also been translated into over 120 languages, including Ukrainian, Swedish, and Hindi.
Major themes in the novel are death and living in a corrupted society, and critics have compared them to Christian allegories. Generally well-received, the book won the 2008 Colorado Blue Spruce Book Award, and the American Library Association named it a "Best Book for Young Adults". A two-part film based on the book began showing in November 2010, when Harry Potter and the Deathly Hallows – Part 1 was released; Part 2 was released on 15 July 2011.
