I actually really like the look of the site, the bookshelf works well imho. I can see where it might get unwieldy as the site expands, but as a main page I think it works really well. Of course this is just my personal opinion and I think the best way to validate what design works best would be to do some A\B Testing on the page. I like the idea of having some books available for free though! Nice work though the site looks really good and it's certainly the type of product I could see my self purchasing.
