The page looks good, although I'm not 100% sure about the background color. I think more spacing (a blank line between paragraphs etc) or sub-headings or the about me in a side box could make the text easier to read.
I think it would be good to tell a bit more about the book, as it has enough to make you curious, but not quite enough for me to be really curious
Also make the payment link REALLY obvious, maybe a text version at the bottom of the page. I'd open the Overview (Preview?) in a new window too, as otherwise I have to remember to hit back.
Check the text carefully. I don't think "Well" should be there, some caps not sure about, "lose" vs "loose".
I think about me section needs a little more work - like I see your pic and why you charge, but it doesn't realy say much on _about me_.
Also, I would explain it's an E-Book to read on your computer. Needs Windows etc.
