Harry Potter is a series of seven fantasy novels written by the British author J. K. Rowling (Joanne Kathleen 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. Harry Potter is the highest-earning book series of all time, earning at least $400 million (not including movies and other merchandise).

From Harry Potter on Wikipedia:

The main story arc features 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. Lord Voldemort killed Harry's parents when Harry was only a year old, and he also tried, but failed, to kill Harry as well, leaving Harry with a distinctive lightning-shaped scar on his forehead, a very mysterious past, and the enigmatic moniker of "The Boy Who Lived."

Since the 30 June 1997 release of the first novel Harry Potter and the Philosopher's Stone, (retitled Harry Potter and the Sorcerer's Stone in the United States) the books have gained immense popularity, critical acclaim and commercial success worldwide. The series has also had its share of criticism, including concern for its increasingly dark themes. As of June 2011, the book series has sold more than 450 million copies and has been translated into 67 languages. The last four books have consecutively set records as the fastest-selling books in history.

A series of many genres, including fantasy, adventure and coming-of-age, Harry Potter also embraces multiculturalism and encourages tolerance. According to Rowling, the main theme is death, although it is primarily considered to be a work of children's literature. There are also many other themes in the series, such as love and prejudice.

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. By 2011, all seven books had been made into eight¹ films by Warner Brothers; the Harry Potter franchise is the highest grossing film series of all time. The series is licensed for select tie-in merchandise, making the Harry Potter brand worth $24 billion.

¹The seventh book was broken into two films, which were released in November 2010 and July 2011 respectively
