"The Wee Free Men." ~ bel

Yes, I do have that one and also "The Amazing Maurice and His Educated Rodents".
"The Wee Free Men" was excellent too. As for Monstrous Regiment, I can see what you mean, but I enjoyed the pleasant conceit of all of the ... well, I don't want to say too much in case it spoils it for anyone. Some of his satires are more obvious than others I guess!

I think I have all of his Discworld books and would be pushed to put them in order of preference (and what would that do for me anyway? Comparisons are odious!). "Small Gods", however, is a particular favourite.

I keep pushing Jasper Fforde. If you like Terry Pratchett, the earlier Tom Holt books and Douglas Adams then you should enjoy Fforde whose books are as unlikely as his name. Not in the least preachy I promise, but they must be read in sequence. He has written three so far, the first one is called "The Eyre Affair".
