Terry Pratchett's fantasy classic Wyrd Sisters, a novel in the
bestselling Discworld series, is the story of Granny Weatherwax, the
most highly regarded non-leader a coven of non-social witches could ever
have.
Generally, these loners don't get involved in anything, mush less royal
intrigue. but then there are those times they can't help it. As Granny
Weatherwax is about to discover, though, it's a lot harder to stir up
trouble in the castle than some theatrical types would have you think.
Even when you've got a few unexpected spells up your sleeve.
Granny Weatherwax teams with two other witches--Nanny Ogg and Margat
Garlick--as an unlikely alliance to save a prince and restore him to the
throne of Lancre, in a tale that borrows--or is it parodies--some of
William Shakespeare's best-loved works.
