Here is a link to try out a little demo of what I have so far. It's a PDF so you might need to install a PDF reader to view it, not sure. Click on the bold text to make choices. Sometimes it doesn't load so you have to move the mouse a little in order for the page to load after making a choice.
I think on a Kindle the text will be underlined in an ePUB format.
