If you only have one book design, how about this:
Still do things in snippets, but tell a story about individual elelemnt of the book
*snippet 1 = focus on the font used, why, interview designer etc
*snippet 2 = what image have you used and why
*snippet 3 = the colours you've used, why you chose these and why they fit in with the story
*snippet 4 = the big launch
It adds a bit of a story behind the experience and gets people immersed in your story - hopefully excited - and you will have a story and reason why you chose what you did. You might just have to think why you did it
Just an idea, but it might help you spread it out
