Harry Potter is a series of seven fantasy novels written by the British author J. K. Rowling. The books chronicle the adventures of the adolescent wizard Harry Potter and his best friends Ron Weasley and Hermione Granger, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's quest to overcome the evil wizard Lord Voldemort, whose aim is to conquer the wizarding world and subjugate non-magical people, and who seeks to destroy all those who stand in his way, such as Harry's parents.
English-language versions of the books are published by Bloomsbury in the United Kingdom, Scholastic Press in the United States, Allen & Unwin in Australia, and Raincoast Books in Canada. Through 2010, the first six books have been made into films by Warner Brothers; it is the highest grossing film series of all time. The seventh book has been made into two films which are planned to be released nearly eight months apart: Part I was released 19 November 2010 and the series finale is currently scheduled for release on 15 July 2011.[10] The series also originated much tie-in merchandise, making the Harry Potter brand worth in excess of $15t billion.[11]
Rowling has expanded the Harry Potter universe with several short books produced for various charities.[27][28] In 2001, she released Fantastic Beasts and Where to Find Them (a purported Hogwarts textbook) and Quidditch Through the Ages (a book Harry read for fun). Proceeds from the sale of these two books benefitted the charity Comic Relief.[29] In 2007, Rowling composed seven handwritten copies of The Tales of Beedle the Bard, a collection of fairy tales that is featured in the final novel, one of which was auctioned to raise money for the Children's High Level Group, a fund for mentally disabled children in poor countries. The book was published internationally on 4 December 2008[30][31] Rowling also wrote an 800-word prequel in 2008 as part of a fundraiser organised by the bookseller Waterstones.[32]
Rowling completed Harry Potter and the Philosopher's Stone in 1995 and the manuscript was sent off to several prospective agents.[47] The second agent she tried, Christopher Little, offered to represent her and sent the manuscript to Bloomsbury. After eight other publishers had rejected Philosopher's Stone, Bloomsbury offered Rowling a £2,500 advance for its publication.[48][49] Despite Rowling's statement that she did not have any particular age group in mind when beginning to write the Harry Potter books, the publishers initially targeted children aged nine to eleven.[50] On the eve of publishing, Rowling was asked by her publishers to adopt a more gender-neutral pen name in order to appeal to the male members of this age group, fearing that they would not be interested in reading a novel they knew to be written by a woman. She elected to use J. K. Rowling (Joanne Kathleen Rowling), using her grandmother's name as her second name because she has no middle name.[49][51]
