I think you should have a longer delay on each book preview in the scrolling list of books at the top. I made it through half of one and then it switched over.

I think you should have a longer delay on each book preview in the scrolling list of books at the top. I made it through half of one and then it switched over. 5 more seconds would be perfect. The "How it works" box isn't very obvious to a first time visitor - maybe you can hang this somewhere off the top next to the logo? I like the arrows on the left and right but I suspect that they would be too far to the sides on a widescreen monitor - I suppose you would know better what resolutions your visitors are using. Otherwise I think the concept is cool, you might benefit from putting this out in the various book forums online.
