It seems like you removed the background altogether -- was that intentional ? The current featureless gray doesn't melt my face like the old background did, but it also looks weird, especially in conjunction with the "About" and "Read an Excerpt" overlays. I still prefer this version over the old one, however.

To be honest, if it were me, I'd probably dispense with the CSS tricks and the gigantic graphics. Instead, I'd just make a regular web page, with regular links, and a modestly-sized image of the cover; then I'd maybe add a "blurbs" section at the bottom. I understand that you are not me, however, so my advice is definitely not worth much; take it with a huge grain of salt.
