The fantastic first book in the Sunday Times bestselling Science of Discworld series When a
wizardly experiment goes adrift the wizards of Unseen University find themselves with a pocket
universe on their hands: Roundworld where neither magic nor common sense seems to stand a
chance against logic. The Universe of course is our own. And Roundworld is Earth. As the
wizards watch their accidental creation grow we follow the story of our universe from the
primal singularity of the Big Bang to the internet and beyond. Through this original Terry
Pratchett story (with intervening chapters from Cohen and Stewart) we discover how puny and
insignificant individual lives are against a cosmic backdrop of creation and disaster. Yet
paradoxically we see how the richness of a universe based on rules has led to a complex world
and at least one species that tried to get a grip of what was going on. Terry Pratchett is
the acclaimed creator of the global bestselling Discworld series the first of which The
Colour of Magic was published in 1983. Raising Steam is his fortieth Discworld novel. His
books have been widely adapted for stage and screen and he is the winner of multiple prizes
including the Carnegie Medal as well as being awarded a knighthood for services to literature.
