Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling. The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The original seven books were adapted into an eight-part namesake film series by Warner Bros. Pictures, making Harry Potter one of the highest-grossing media franchises of all time.
