Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but which looks completely different. Particularly as it’s carried though space on the back of a giant turtle (sex unknown). It plays by different rules. But then, some things are the same everywhere. The Disc’s very existence is about to be threatened by a strange new blight: the world’s first tourist, upon whose survival rests the peace and prosperity of the land.

A nightmarish danger threatens from the other side of reality. . . . Armed with only a frying pan and her common sense, young witch-to-be Tiffany Aching must defend her home against the monsters of Fairyland. Luckily she has some very unusual help: the local Nac Mac Feegle—aka the Wee Free Men—a clan of fierce, sheep-stealing, sword-wielding, six-inch-high blue men.

It was the body of a tall stout man. On his dead face, a handsome pair of gold pince-nez mocked death with grotesque elegance. The body wore nothing else. Lord Peter Wimsey knew immediately what the corpse was supposed to be. His problem was to find out whose body had found its way into Mr Alfred Thipps' Battersea bathroom.

At six years old, Terry was told by his headteacher that he would never amount to anything. He spent the rest of his life proving that teacher wrong. At 66, Terry had lived a life full of achievements: becoming one of the UK's best-selling writers, winning the Carnegie Medal and being awarded a knighthood for services to literature. Following his untimely death from Alzheimer's disease, the mantle of completing Terry's memoir was passed to Rob Wilkins, his former assistant, friend and now head of the author's literary estate.

Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but that looks completely different. It plays by different rules. Certainly it refuses to succumb to the quaint notion that universes are ruled by pure logic and the harmony of numbers. But just because the Disc is different doesn't mean that some things don't stay the same.
