The kindle version will be release in the future, hopefully soon. We're planning to make some revisions to the book based on some of the feedback (as well as adding/updating the links at the end of each section). So in the short term, the Holloway reader will be the best place to read the book as these revisions are made.
Josh with Holloway here. As David mentioned, this title does not currently include a download to load on to your Kindle. (Most of our readers prefer the online Holloway Reader, and we publish in that format because it's a more powerful reading experience with search, commenting, and easier content updates.)
But yes we do add PDF and EPUB formats when there is enough demand. And no downloads do not require repurchase. If you purchase now you are getting online access plus future content updates as well as future download formats that are added. Hope that helps!
