In the fifth book, Harry Potter and the Order of the Phoenix, Harry must confront the newly resurfaced Voldemort. In response to Voldemort`s reappearance, Dumbledore re-activates the Order of the Phoenix, a secret society which works from Sirius Black`s dark family home to defeat Voldemort`s minions and protect Voldemort`s targets, including Harry. The Order includes many of the adults Harry trusts, including Remus Lupin, Sirius Black, and members of the Weasley family, but also some surprising members; the loyalties of some characters are not so obvious. Despite Harry`s description of Voldemort`s recent activities, the Ministry of Magic and many others in the magical world refuse to believe that Voldemort has returned.
