I recently made an E-book of Abraham Lincoln's (yes that Abraham Lincoln) The Trailor Murder Mystery, short story, with the Calibre editor. But when I open the book in the Calibre E-book viewer the progress counter reads 94% on the final page. If I shrink the viewer window, or make the text bigger, so some of the final page's text moves onto another page, it reaches 100%. I've ran the bug checker, and which returns a "No problems found" message. I've also ran the book though multiple online validators, which return no errors.

At first I thought it might be a problem with my CSS file, which I re-wrote. Then rebuilt the whole book. Yet still no dice. After going through my code multiple times, and having my brother take a look. Neither of us can figure out what is causing the problem.

Funnily enough if I convert the file to mobi, it works perfectly. Yet creating an Epub or AZW3 the problem persists.

I've attached the book and an image showing the problem I'm encountering. Any help in solving the problem would be greatly appreciated.
