The acclaimed Science of Discworld centred around an original Pratchett story about the Wizards of Discworld. In it they accidentally witnessed the creation and evolution of our universe, a plot which was interleaved with a Cohen & Stewart non-fiction narrative about Big Science. In The Science of Discworld II our authors join forces again to see just what happens when the wizards meddle with history in a battle against the elves for the future of humanity on Earth. London is replaced by a dozy Neanderthal village. The Renaissance is given a push. The role of fat women in art is developed. And one very famous playwright gets born and writes The Play. Weaving together a fast-paced Discworld novelette with cutting-edge scientific commentary on the evolution and development of the human mind, culture, language, art, and science, this is a book in which 'the hard science is as gripping as the fiction'. (The Times)

A talking cat, intelligent rats, and a strange boy cooperate in a Pied Piper scam until they try to con the wrong town and are confronted by a deadly evil rat king.

Terry Pratchett's lovable nomes return in "Diggers," the second book of the Bromeliad trilogy. It's an improvement on the first book "Truckers," with a steadier pace and a new twist on this tiny-aliens-among-us plotline. It gets a bit silly at times, but doesn't wear out its welcome.When last seen, the peculiar, lovable nomes had managed to drive a truck away from the Arnold Bros. store, and had set up a new home in an abandoned quarry. Masklin and his little band are doing fine, although many of the more pampered nomes are having to get used to the idea of farming and living in a place with no heating and too much open space.Then everything changes. A human brings a paper to the quarry, and the nomes learn that the quarry is going to be reopened — and the nomes risk discovery unless they can find a new place to live. When Masklin ventures off to the mysterious Florida, to find the descendent of Arnold Bros., a fanatic called Nisodemus takes the opportunity to rally th...

"May you live in interesting times" is the worst thing one can wish on a citizen of Discworld -- especially on the distinctly unmagical sorcerer Rincewind, who has had far too much perilous excitement in his life. But when a request for a "Great Wizzard" arrives in Ankh-Morpork via carrier albatross from the faraway Counterweight Continent, it's he who's sent as emissary. Chaos threatens to follow the impending demise of the Agatean Empire's current ruler. And, for some incomprehensible reason, someone believes Rincewind will have a mythic role in the war and wholesale bloodletting that will surely ensue. (Carnage is pretty much a given, since Cohen the Barbarian and his extremely elderly Silver Horde are busily formulating their own plan for looting, pillaging, and, er, looking wistfully at girls.) However, Rincewind firmly believes there are too many heroes already in the world, yet only one Rincewind. And he owes it to the world to keep that one alive for as long as possible.
