I reckon it is one of his weaker ones to be honest Sarah.. Though this is my 2nd reading ( Had it in hard back and lost it, so Mo bought it for me in paperback )
I do agree he does not write the quick enough though !
About the only ones I aint got are the plays and stuff like that.. I have the Disc World science volumes, and the Disc World Companions ( I even have a very small booklet he wrote with an obscure little man about Falconry.. )
I love any book with Rincewind or Twoflowers in, and some of the books with the watch heavily themed are ok ( such as Men at Arms ), but others ( Feet of Clay spring to mind ) read as if the author is a struggling detective thriller writer rather than a leading exponent of the Sci Fan league.
Have you read Hat Full of Sky yet ? It features the dread MacNac Feegle again ..
