I let the KDP select exclusivity run out on Kevin and the Seven Lions. It is now up a Nook. Kobo and iBooks should be coming soon. But let me just say a blog post is coming about this experience. Just uploading the book to Nook, Kobo, and Apple was a quick lesson in why Amazon is winning. That blog post is coming. It is a big learning experience.
Anyway here is the link for Seven Lions on Nook.
