The Colour of Magic, the first novel in Terry Pratchett's wildly imaginative Discworld series, takes the listener on a remarkable journey. The magical planet of Discworld is supported by four massive elephants who stand on the back of the Great A'Tuin, a giant turtle swimming slowly through the mysterious interstellar gulf. An eccentric expedition sets out to explore the planet, encountering dragons who only exist if you believe in them, and, of course, "The Edge" of the planet.

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place which might sound and smell very much like our own, but which looks completely different.... Collected together for the first time are seven full-cast BBC Radio dramatisations of Terry Pratchett’s novels, with star-studded casts including Martin Jarvis, Sheila Hancock, Anton Lesser, Philip Jackson, Alex Jennings and Mark Heap.

The Company builds planets. Kin Arad is a high-ranking official of the Company. After 21 decades of living, and with the help of memory surgery, she is at the top of her profession.

In the 'fantasy' universe of the phenomenally bestselling Discworld series, everything runs on magic and common sense. The world is flat and million-to-one chances happen nine times out of ten. Our world seems different - it runs on rules, often rather strange ones. Science is our way of finding out what those rules are. The appeal of Discworld is that it mostly makes sense, in a way that particle physics does not.
