'Destiny is important, see, but people go wrong when they think it controls them. It's the other way around.' 
 
Three witches - Granny Weatherwax, Nanny Ogg and Magrat Garlick - have gathered on a lonely heath. A king has been cruelly murdered, his throne usurped by his ambitious cousin. An infant heir and the crown of the kingdom, both missing . . .
