It's available for free here if you, or anyone else want to take a peek

That's because it is a fixed layout ebook. The only change you can make is using the zoom option and that is pretty much useless for this ebook. I was also noticing that the dropcaps (another idea that should never be used in an ebook) are not done properly.

Other items: the ebook does not have a cover image as such. When I imported it into calibre, the title was "Petrified Minds TRIPLE KINDLE FINAL.mobi" and the author was unknown. The xhtml navigation document has a PageList but no ToC entries which is yet another standard violation. It looks as if a goodly chunk of the stylesheet is missing (Indented-Paragraph, Drop-Cap, Chapter-Title, etc., etc.).

Somewhat interestingly, from the content.opf, this epub is intended to be read in landscape with the pages carefully labelled as left/right and the Apple metadata to allow using embedded fonts is present:

    <meta property="ibooks:specified-fonts">true</meta>
    <meta property="rendition:layout">pre-paginated</meta>
    <meta property="rendition:orientation">landscape</meta>
    <meta property="rendition:spread">both</meta>

    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-1" properties="page-spread-right"/>
    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-2" properties="page-spread-right"/>
    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-3" properties="page-spread-left"/>
    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-4" properties="page-spread-right"/>
    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-5" properties="page-spread-left"/>
    <itemref idref="Petrified_Minds_TRIPLE_KINDLE_FINAL.mobi-6" properties="page-spread-right"/>

Overall, the kindest thing I can say about the structure of the epub is that it's an abomination. I've attached some screenshots from my Forma. Likely the same crap you've already seen.
