If Terry Pratchett has a weakness, at least in his early books, it's that it takes some effort to get into the story. I'm a huge Pratchett fan, but I've found that certain of his books are just plain difficult to get into the flow of. Sourcery was one of those books. I guess this can be attributed to several things, for one that it's one of his earliest books, and hence his skill had not yet reached its peak. He hadn't yet developed all the characters I've come to love, such as the Ridcully and the faculty, so I had to deal with the usual throwaway wizards that populated his early books focused on the wizards. He had not yet developed his ability to tie comedy and story as flawlessly as he managed to in later books.
