It seemed an easy job ...

After all, how difficult could it be to make sure that a servant girl doesn't marry a prince?

But for the witches Granny Weatherwax, Nanny Ogg and Magrat Garlick, travelling to the distant city of Genua, things are never that simple ...

For one thing, all they've got is Mrs Gogol's voodoo, a one-eyed cat and a second-hand magic wand that can only do pumpkins. And they're up against the malignant power of the Godmother herself, who has made Destiny an offer it can't refuse. And finally there's the sheer power of the Story.

Servant girls "have" to marry the Prince. That's what life is all about.

You can't fight a Happy Ending.

At least - up until now ...
