[Plugin: WPBook] Only Recent Posts work

Generally this is an issue with permalinks, and what you’ve set your canvas callback url to.

Your blog lives at http://www.motorz.tv/blog/ – but your permalinks looks like this: http://www.motorz.tv/2314/featured-products-at-website/

Your canvas callback url has to be http://www.motorz.tv/ in that case – which means users will see some version of your home page rather than your /blog/ page – support for custom home pages (basically a setting which allows you to either override your custom home page or show it) is coming in WPBook 1.5 or later.

WPBook tries to find the story at:
http://www.motorz.tv/blog/2314/featured-products-at-website/

(It adds the permalink for the entry to the canvas callback url)

So the alternative is to define your permalinks to look like that, or change your canvas callback url to NOT include the /blog/ part.
