Have you added any new images to the book? If yes, remove them, and try again. Perhaps you added a photo, that cannot be processed.
If the book is unchanged, try, if reairing your Aperture library will help.
- Repair your Aperture library using the Aperture Library First Aid Tools: Hold down both keys ⌥⌘ together firmly, and continue to hold them down, while you are double clicking the library icon, until you are seeing the First Aid panel. Select "Repair Database". This may take a while for a large library.
