In terms of worldwide sales (around 25 million copies to date, and no signs of stopping), Terry Pratchett is one of the leading writers in English. He is also a writer of complexity and allusiveness, whose rich work raises important issues about the real world within a fantasy/comic environment. This encyclopedia mixes shorter entries conveying specific information for foraging readers with longer, more discursive articles for readers wanting more reflective engagement with Pratchett's novels. Entries on novels and characters not only highlight Pratchett's celebrated inventiveness but also analyse the underlying meanings. Entries on 'Fantasy', 'Science Fiction', 'Fairy Tales' and related topics situate the novels within literary genres, and other articles discuss the scientific, social and philosophical idea underpinning Pratchett's playful but sophisticated narratives. Associates and collaborators, such as Douglas Adams, Neil Gaiman and Ian Stewart, feature in articles discussing contemporary influences, and plentiful information about the fascinating peripheral detail of audio editions, radio broadcasts, TV adaptations and film scripts enhance the fun. A Companion to the Novels of Terry Pratchett is essential reading for fans who want to unpick the allusions and appreciate the rich complexity of one of the great bodies of contemporary popular literature.
