Re: I'm touched by the weirdness of this request...
Most of the Discworld novels are standalone and can be read in any order, however it is *suggested* by the author to read from the beginning (The Colour of Magic) and the witch books (Wyrd Sisters, Witches Abroad, Lords and Ladies, Masquerade and Carpe Jugulum really do need to be read in order. Enjoy, Pratchett's work is brilliant.
