Use the following template for a nicely presented post:

To solve this, I propose that each novel template, for example "Cite book/Cormyr: A Novel", has its own set of subtemplates, for example "Cite book/Cormyr: A Novel/Paperback" and "Cite book/Cormyr: A Novel/Hardcover" so that it's easy to specify which edition is being cited, and the page numbers will make sense.
Also, but this is quite drastic, I think that the old template should be changed, so that it won't allow an editor to use it unless an edition is specified. So, when someone uses "Cite book/Cormyr: A Novel" without giving the edition, it will display "Warning: edition not specified" or similar text. This will have the short-term downside of affecting all the existing citations for novels, but the advantage that new editors will immediately see that using a novel citation without an edition is not valid.
