JK Rowling reveals title of first adult novel

Author JK Rowling has announced her first adult novel will be called The Casual Vacancy.

The Harry Potter writer revealed in February that she was working on the book, and said it would be "very different" from her previous material.

The book will be published worldwide in hardback, e-book and as an audio download and CD on 27 September.

Speaking to the BBC's Lizo Mzimba at the final Harry Potter film premiere in 2011 Rowling said: "I didn't want to publish again until the last film was out".
