Wyrd Sisters

Original cover to Wyrd Sisters, by the late Josh Kirby

Terry Pratchett is probably one of the finest writers of fantasy out there. Yes, he's funny as hell, but it's his slightly absurd view of our own world that infuses his Discworld with it's life.

BBC Four Xtra has been running a few dramatizations of his best known books. Wyrd Sisters, the first one to deal with Granny Weatherwax and her coven properly, is a great riff on Shakespeare- check it out. It's a great place to jump into the Discworld for the first time, and the link is good for about a week, so hop to it.
