The wizards of Unseen University are again called upon to defend their creation, Roundworld, this time in a courtroom—where its very existence hangs in the balance.

The Omnians fervently believe that the world is round, not flat, and view the discovery of Roundworld as a vindication of their faith. To leave this artifact in the hands of the wizards would be unacceptable. Not only do the academics hold that Discworld is flat, but by creating the Roundworld universe, they have elevated themselves to the level of gods. Ankh-Morpork’s venerable tyrant Lord Vetinari agrees to a tribunal, where the wizards Ridcully, Rincewind, and Ponder Stibbons can present their case—with key assistance from a Roundworld librarian named Marjorie Daw.

JUDGMENT DAY weaves together explorations of such Earthly topics as big science, creation, subatomic particles, the existence of dark matter, and the psychology of belief--a treat for Discworld fans and readers of popular science alike.

From Publishers Weekly:

Half popular science essay and half fantasy tale, the final installment of the enjoyable Science of Discworld series sums up by updating topics from previous books while exploring the nature of our universe and the psychology of human belief. Ever since the wizards of Discworld's Unseen University accidentally created "Roundworld"�€”aka Earth�€”they've been befuddled and fascinated by this strange world that "swims through space" without the benefit of resting on four elephants and a giant turtle (unlike the perfectly normal, and quite flat, Discworld). After six years of protecting Roundworld from destruction in its own space, the wizards now face a Discworld-born threat: the Omnian church, which is certain that Discworld is spherical, has laid claim to Roundworld as vindication of their faith. The wizards' story chapters frame essays on science-related topics such as the Big Bang, particle physics, and the Anthropic Principle, as well as belief systems, creation myths, and the Flat Earth Society. While the fantasy frame here is weaker than those in previous books, the investigations of the late Pratchett's pragmatic wizards�€”when they aren't distracted by the last chocolate biscuit on the tea tray�€”provide a firm foundation for science coverage from mathematician Stewart and zoologist Cohen, reminding readers that "scientific revolutions don't change the universe. They change how humans interpret it." Agent: Colin Smythe, Colin Smythe Limited. (Dec.)\n
