It will be called Harry Potter and the Deathly Hallows. The announcement was made on the writer's official website.

Despite the publication date not being known, the book is tipped to be a big seller, like the rest in the series

Speculation about the plot has surrounded the book after Rowling admitted two characters will die - some think it could be Harry Potter himself.
