If this is you then there’s nothing to stop you enhancing your book beyond what Book Creator can do. Just grab an exported ePub file from Book Creator and follow the instructions below to access the underlying files within the ePub.

How to do it
ePub files are nothing more than zipped archives of web pages, with some extra files and conventions detailing the book. However the ePub spec does require the zip archive to be constructed in a specific way. The instructions below will keep you sane!
To correctly unzip and zip ePub files on a Mac we recommend using a couple of scripts written by Dan Rodney. Download the scripts from ebookflightdeck.com, then run ePub Unzip and ePub Zip to work with your file.
For Windows users things are a bit easier. You can just change the file extension from .epub to .zip and then extract the files. When you’re all finished right click on the folder and choose Send to > Compressed (zipped) folder, then change the file extension back to .epub.
Good luck! And don’t worry if your ePub stops working – you can always re-export it from Book Creator.
