Interesting to read the different opinions. I enjoyed the book (although I wanted to argue with some of the ideas in it!) and found it to be very Pratchettian - typical themes, typical plot devices, typical characterisation. I was intrigued by his rather obvious avatar insertion at the end, with the old guy and the telescope. Is Pterry veering towards the spiritual side of agnosticism these days?

The Garner who cares.
