SIR Terry Pratchett's final novel has gone on sale.

The Shepherd's Crown is the 41st novel in the Discworld series and fans gathered at bookshops across the UK to grab their copy.

The fantasy author, who lived in Broad Chalke, died at the age of 66 in March after a long battle with Alzheimer's disease.

His books which he described “as an antidote to bad fantasy” sold 85 million copies worldwide and were translated into 36 different languages.

The setting for Discworld, which was a flat planet floating through space on the back of a giant turtle, was imaginary but it often satirised aspects of modern life.

The first of Pratchett’s Discworld novels, The Colour of Magic, was published in 1983.

His books generated adaptations for the stage, radio and television, with Salisbury amateur dramatic group Studio Theatre producing adaptations of Going Postal and Making Money.
