Wyrd sisters.

As I was reading this book I was reminded of one of Nigella Lawson's cooking porn shows, in which she said she didn't know if she actually liked drinking tea or if she had convinced herself she liked it because she knew it was good for her.

I've attempted Pratchett before and found him hard-going, as I have with Douglas Adams and Ben Elton, who write in the same style. They take a lot of effort and, although I had a lot of I see what you did there moments, and a few genuine laugh-out-loud moments, I don't know that the effort I had to put in was repaid by the enjoyment I got back.
