It is very easy to just "enjoy" a Terry Pratchett novel. The general mayhem and giggles hiding a deeper truth. I have read most of Mr Pratchett's novels and enjoyed almost every one. This, one of later novels, darker than most but still clever and enthralling gave me pause to recall all the good things about them. When you put aside the good nature, the enjoyment, the silly asides and the overall bewilderment you remember why "Terry" of all comedy fiction writers holds such high esteem among readers. He could really write, pulling you from horror to hilarity in a paragraph, this novel is another classic. Dark, dreadful, deliberate and deliriously funny. Another cracker in Terry's tin.
What a great writer.
