TERRY Pratchett has died aged 66 after suffering from Alzheimer's disease.
The much-loved fantasy writer leaves behind him a vivid legacy of more than 70 books that sold over 85 million copies in his lifetime.
Best known for his ever-popular Discworld series, Pratchett's passion for the written word proved almost uncontainable.
