Witches Abroad - A Novel of Discworld | Terry Pratchett

Trying to make sure a servant girl doesn't marry a prince, witches Granny Weatherwax, Nanny Ogg and Magrat Garlick have their work cut out. For one thing, all they've got is Mrs Gogol's voodoo, a one-eyed cat and a second-hand magic wand; and you can't fight a happy ending, can you?
