When the first novel of the series, Harry Potter and the Philosopher's Stone (published in America and other countries as Harry Potter and the Sorcerer's Stone) opens, it is apparent that some significant event has taken place in the Wizarding World – an event so very remarkable, even Muggles (non-magical people) notice signs of it.The full background to this event and Harry Potter's past is revealed gradually through the series.As Harry develops through his adolescence, he learns to overcome the problems that face him: magical, social and emotional, including ordinary teenage challenges such as friendships, infatuation, romantic relationships, schoolwork and exams, anxiety, depression, stress, and the greater test of preparing himself for the confrontation that lies ahead in wizarding Britain's increasingly-violent second wizarding war.The books also contain many flashbacks, which are frequently experienced by Harry viewing the memories of other characters in a device called a Pensieve.The success of the books and films has allowed the Harry Potter franchise to expand, with numerous derivative works, a travelling exhibition that premiered in Chicago in 2009, a studio tour in London that opened in 2012, a digital platform on which J. Rowling updates the series with new information and insight, and a pentalogy of spin-off films premiering in November 2016 with Fantastic Beasts and Where to Find Them, among many other developments.Most recently, themed attractions, collectively known as The Wizarding World of Harry Potter, have been built at several Universal Parks & Resorts amusement parks around the world.The original seven books were adapted into an eight-part film series by Warner Bros.
The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly eleven million copies in the United States within twenty-four hours of its release.
Instead, the unexpected happened: Harry survived with only a lightning-shaped scar on his forehead as a memento of the attack and Voldemort disappeared soon afterwards, gravely weakened by his own rebounding curse.
As its inadvertent saviour from Voldemort's reign of terror, Harry has become a living legend in the Wizarding World.
The central character in the series is Harry Potter, an English boy who lives with his aunt, uncle, and cousin - the Dursleys - who discovers, at the age of eleven, that he is a wizard, though he lives in the ordinary world of non-magical people known as Muggles.
The wizarding world exists parallel to the Muggle world, albeit hidden and in secrecy.
