I would make the "How Bookhu works" box stand out a little more. One thing I've noticed with all of the "review my startups" is that we have no idea what we are going to initially generally, and when we get there the first thing we want to know is - what does this site do. You explain it well enough, I would just make the box pop a little more visually so I don't spend as much time hunting around for it. I found the site interesting enough to poke around a bit. Visually I thought it looked pretty good. I would probably make the call to action more obvious as well. Don't be afraid to tell people what you want them to do. The buy links are pretty small and not even very clear that I am buying them by clicking on them. Make them very obvious. The "Leave a Reply" at the bottom doesn't make sense to me. What am I replying to? Is it just a spot for people to leave their thoughts on the book? Again, tell me what you want. Perhaps you could form it as a question. Try some different things and see what gets people to start submitting comments or reviews or whatever it is you're looking for there (or just take it out). Overall thought I thought it looked pretty nice and it will be interesting to see how you do.
