A delightfully funny, fantastically inventive collection of twenty unearthed short stories by Sir Terry Pratchett, the award-winning and bestselling author and creator of the phenomenally successful Discworld fantasy series. These rediscovered tales were written by Terry Pratchett under a pseudonym for British newspapers during the 1970s and 1980s. The stories have never been attributed to him until now, and might never have been found—were it not for the efforts of a few dedicated fans.

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.
