Witches Abroad

What could be easier than preventing a servant girl from marrying a prince, especially for 3 clever witches? But Granny Weatherwax, Nanny Ogg, and Magrat Garlick face more than they bargained for when they journey to the distant city of Genua. For one thing, their power is limited to Mrs. Gogol's weak voodoo spells, a one-eyed cat, and a second-hand magic wand that only works on pumpkins. Furthermore, the Godmother has made Destiny an offer it can't refuse. Do servant girls have to marry the prince? Is that what life's all about?
