A Cover Picture and the cover text would definitely be too much. You're trying to list your relevant skills not make a sale to them.
In CV's that are specific and rigid, e.g some companies give you a blank template that you must fill in then placing this in the section called 'Other', this would probably be the best place to list them in this kind of format:
Written book on 'Genetic Engineering' called "How to breed wrestling plants", published 2004 - ISBN 1337
This then shows what its about, what its called and when it was written.
If you received any awards for your books then listing those underneath would be a good idea too to highlight how well received your books were.
If you have the freedom to write your CV as you choose then an alternate option is to highlight that you have this experience by having a specific section titled 'Publications' where this relevant information can be listed as above.
This would also aid you in drawing more attention to this experience than putting it in other.
