First the suggestion: if you are a Pratchett fan, DO NOT miss Good Omens, a book he co-wrote with Neil Geimon (sp). The book is classic Pratchett, and simply amazing if you liked his Discworld series.
Question: is the wee-free-men series part of discworld? I was looking at them on amazon and they didn't appear to be discworld but could anyone who has read them enlighten me? Thanks!
