Holly Cupala has the most interesting trailer for her novel, Don’t Breathe a Word.
Although she didn’t say so, I think this could be what illustrations in ebooks will look like in the future: Short scenes, maybe a few seconds long each, embedded in the ebook itself. The author herself may shoot the videos (and readers would enjoy the earnestness of the effort), or hire a professional.
For those who prefer the graphic arts, another trailer uses illustrations drawn by Realm Lovejoy.
So this is an impressive book launch by Holly Cupala, as well as a nice mini-tour of Seattle.
