Judgement Day
Order in Court!
On Discworld an almighty row is brewing...
The Omnians want control of Roundworld - its very existence makes a mockery of their religion. The wizards of Unseen University, however, are extremely reluctant to part with it. After all, they created it!
Enter Roundworld librarian, Marjorie Daw (accidentally, through L-space). Perhaps, with her Jimmy Choos and her enquiring and logical mind, she can help? Especially as she's the sort of librarian who thinks that the Bible should be filed under Science Fiction and Fantasy.
Lord Vetinari presides over the tribunal. People on both sides are getting extremely angry, There are some very big questions being asked - and someone's got some explaining to do...
The fourth in the Science of Discworld series, JUDGEMENT DAY sees Terry Pratchett, Professor Ian Stewart and Doctor Jack Cohen create a mind-mangling mix of fiction, cutting-edge science and philosophy in an attempt to answer the REALLY big questions - this time taking on God, the Universe and, frankly, Everything Else.
Proceed with caution, you may never look at your universe(s) in the same way again.

Terry Pratchett
Terry Pratchett’s work was nothing short of magical, blending satire, wit, and a deep love for the absurd with stories that could make you laugh, think, and occasionally question reality. Born in 1948 in Beaconsfield, England, Pratchett's sharp humor and keen observations of human nature started early. After a series of journalistic jobs and a stint in publishing, he found his true calling as a writer of fantasy—albeit with a twist.
Pratchett’s most famous creation, the Discworld series, is a sprawling, multi-layered universe filled with quirky characters, sharp satire, and an unrelenting exploration of the complexities of society. The series—spanning over 40 novels—introduces readers to a world supported by four giant elephants standing on the back of Great A’Tuin, the giant turtle swimming through space. It’s a place where witches, wizards, and talking cats wander through settings that are both fantastical and familiar, a perfect mirror to our own world, full of politics, absurdity, and endless curiosity.
