Which final Harry Potter novel did J.K. Rowling publish in 2007?

J.K. Rowling published Harry Potter and the Deathly Hallows in 2007 as the final Harry Potter novel.

Bloomsbury released the book in the United Kingdom on 21 July 2007, with simultaneous publication in many markets. The story follows Harry, Ron, and Hermione as they leave Hogwarts to search for Horcruxes and confront Voldemort. It resolves the central conflict that began in the first novel.

Deathly Hallows was the seventh book in the series. Rowling had announced that it would be the final main Harry Potter novel, although later works expanded the franchise through stage drama, reference material, and screen stories. The book became one of the fastest-selling novels in publishing history.

The title refers to three legendary magical objects: the Elder Wand, the Resurrection Stone, and the Cloak of Invisibility. These objects connect the book’s plot to its themes of death, sacrifice, and the desire to overcome mortality.
