Thanks for writing us about this; we're glad you're interested in the book. We currently don't have samples or previews for books we distribute for other publishers (this one is published by Rosenfeld Media), and I agree this is something we should think about adding.
In the meantime, you can preview the book on Safari Books Online at http://my.safaribooksonline.com/9781457102691?portal=oreilly&cid=orm-cat-readnow-9781457102691. You can also view the book's blog, Table of Contents, and diagrams and images on Rosenfeld's site at http://rosenfeldmedia.com/books/science-fiction-interface/
I hope that helps!
