I like it. It would be nice if the buy button was more prominent. I found a book I was interested in buying, or at least finding more about. I tried clicking on the book cover and nothing happened. I did notice the Buy button in the top right at the end, but it's not prominent as it's the same colour as the shelf.
A/B test with red - I'll bet you a drink red outperforms green. (Oh, and make sure your conversion isn't clicks, but purchases. I believe the Associates API will let you track by click. And, no Pek, we don't do that tracking at Dawdle. :( )
