If you open the book in the Kindle or iOS Books app and the device is in landscape orientation, you have the choice to display it like a book, with left and right pages, rather than a single page full screen, like this:

This is how I prefer to read e-books. Notice how the chapter begins on the left page. If the chapter ends on a left-hand page, the right-hand page opposite it should be empty, like this:

Here, you can see the L/R page view on the left, in which the chapter ends part way down the left-hand page, and you can see the next chapter (Prologue) beginning on the left side of the next 2-page L/R view:

Again, notice that the right-hand page before the Prologue is blank. This is what I am trying to achieve, but in my e-book, if a chapter ends on a left-hand page, the next chapter begins on the right-hand page opposite it. I need to generate that empty RH page where applicable.
