How do you brand the digital book of the future? 50% old school, 50% new school.
From a design standpoint, Kindle books aren't radically different than their print counterparts. Letters are rendered in pixels rather than ink, and are somewhat adjustable. But otherwise, a digital a book is the same as an book. So whether it's a platform like Kindle or a more traditional publisher like Penguin, these brands tend to stick with traditional, typography-based wordmarks.
