Have you read it, Esme?
Here's a review from a friend of mine on a Pratchett site:
Nope, hard to get postage in the 'ghan...instead we 'borrowed' a copy from my boss who was silly enough to leave a copy he brought back from the UK on his last leave...official word is that 11 out of 14 pers in our Flight would read this again, 2 are still reading it and 1 can't read (unless it is in REALLY big crayon).
Well worth a 2nd read and then a third just to make sure you didn't miss anything the 2nd time around.
I give it 4 out of 5 slightly used farthings.
