Witch-in-training Tiffany Aching hadn't expected magic to involve chores and ill-tempered nanny goats! But as Tiffany purses her calling, a sinister monster pursues Tiffany and neither Mistress Weatherwax (the greatest witch in the world) nor the six-inch-high Wee Free Men (the greatest thieves in the world) can defeat it. When the monster stikes, Tiffany will have to save herself-if she can be saved at all!.
