I'm sorry, I've been somewhat neglecting this discussion lately. 
Been going through a major downer the last few weeks and haven't had much enthusiasm for anything.
Anyhow - when I first read this book it took me a while to 'get' the bit where Granny controls the unicorn. My first thought was the description of "iron-grey hair", but that didn't make any real sense and it wasn't until I found out more about unicorns that I understood Granny's qualifications.
I think this goes back to one of the themes of the book - alternative universes. The Granny in many of those certainly couldn't have controlled the unicorn and may even have been killed by it.
I do like the way that Terry makes his readers think and learn.
