Tiffany Aching is a young witch, social worker, and cheese maker extraordinaire. She hails from a long line of shepherds and has a powerful connection with the Chalk where she lives. Wherever Tiffany goes, it's almost certain that a horde of tiny fighting, drinking blue men in kilts - the Nac Mac Feegle - won't be far away. The five books follow Tiffany from age nine through to young adulthood, each dealing with a different stage of growing up and learning what it means to be a witch. The series connects back to the Witches sub-series, with Granny Weatherwax serving as Tiffany's mentor. The Shepherd's Crown, the final Discworld novel, serves as a conclusion to both Tiffany's story and the series as a whole.
