I really like the design, and the idea is nice. One suggestion I have is making some way to add books from your My Shelf page. I didn't see a way easily, and ended up just going to the browse page. I'm assuming that's probably the flow you want, but you may want to have a plus button or something on the shelf UI that links to the browse page for books.

You should be able to. Once you are logged in, when you hover over any book on the shelf view, you click on 'Shelf it' to immediately add it to your shelves.
