I loved the idea and wanted to use it for my site, but I also wanted to give my reviews of the books and thought it would be fun if you could click the books to expand them.
When I see this I think about the animations, spotting small UX oddities that go against convention.
I can't remember a thing about the books though.
And that is why Amazon don't present their books like this!
Keep going though, but you have to have things like text at an agreed minimum font size and you have to make the interface accessible. Only if you have thought through those parts and got solutions can you dare to do anything new these days online.
I sound critical but I like seeing things like this far more than Amazon's web pages, it is just theirs get my money.

The interaction is a bit of an oversight on my part, you have to click the pop-up to close it.
