Thanks DMSmillie. I'm in good shape now.

I looked at the NCX file long enough until it made sense. For whatever reason, on export the navPoint tags were overlapping. So instead of:

<navPoint id="navPoint-2" playOrder="2">
<navLabel>
<text>Title Page</text>
</navLabel>
<content src="Text/title.xhtml"/>
</navPoint>
<navPoint id="navPoint-3" playOrder="3">
<navLabel>
<text>Preface</text>
</navLabel>
<content src="Text/Preface.xhtml"/>
</navPoint>

The code looked like

<navPoint id="navPoint-2" playOrder="2">
<navLabel>
<text>Title Page</text>
</navLabel>
<content src="Text/title.xhtml"/>
<navPoint id="navPoint-3" playOrder="3">
<navLabel>
<text>Preface</text>
</navLabel>
<content src="Text/Preface.xhtml"/>
</navPoint>
</navPoint>

So each chapter was within the illustration's navPoint, so I was only going to the illustration.

Thanks for the help, everyone.
