Terry Pratchett's final Discworld book, The Shepherd's Crown, has been given a release date.

The fifth novel featuring headstrong young witch Tiffany Aching will be published in hardback, ebook and audio on 10 September, after the late author finished writing it last summer. There will also be a special collector's edition.

Previous Tiffany Aching stories include The Wee Free Men, A Hat Full of Sky, Wintersmith and I Shall Wear Midnight.

Another Pratchett novel, The Long Utopia, will be published in June to complete his catalogue of more than 70 books.

Co-written with sci-fi author Stephen Baxter, the fourth work in The Long Earth series will be set in a universe of infinite parallel Earth’s that characters can travel between simply by stepping.
