Daniel Radcliffe, Rupert Grint and Emma Watson, actors of Harry Potter, Ron Weasley and Hermione Granger always thought that, of course, everything J.K.Rowling wrote is fiction and fake... or so they thought, until some mysterious strangers come and kidnap them. After learning that the wizarding world is real, they must help Harry and his friends defeat Voldemort.

When Harry walks to the back porch of the Dursleys to get the mail, as always, he finds a girl with almond green eyes dozing off. Who is this girl, and why is she here? Harry finds out many hidden secrets-as well as his long-lost sister.
