Have you just read all of TP's books?!!
@firstname.lastname@example.org I did just read all of mainline discworld novels (41 books I think) - first time through, have enjoyed them all, feel like this last novel was an almost perfect end.
@email@example.com they're such light reading that it was a pleasure to read them all - and I liked the way I read them (publication order), I might one day reread them by character arc (e.g. Witches Arc, Wizards Arc, City Arc)... But I do recommend the entire series :)
