The Kindle Web App Redux
Here is the other title featuring the Kindle Web App, The First Assassin by John J. Miller. This app is still in beta. As of today I haven't seen any other books with the green "Read First Chapter FREE" button. The app will feature settings for text size, background color, words per line, and line spacing. Besides the embed button, there is also a sharing button that allows you to share the app on either Twitter or Facebook. Additionally you may expand the Web app to full screen mode for easier viewing.
