Really exciting novels are rare.  But rare books are expensive.  Therefore, Really exciting novels are expensive. Here, the word "rare" is used in different ways in the two premises of the argument, so the link they seem to  establish between the terms of the conclusion is spurious. In its more subtle occurrences, this fallacy can
