Okay, I totally agree it is a bad idea to judge a book by its cover. However, Nicolas Carr's Big Switch ("The Big Switch: Rewiring the World, From Edison to Google") has quite a compelling teaser on its jacket. I haven't started reading the book though.
It says that a hundred years ago, companies stopped producing their individual power and joined newly created electrical power grids. Something like that is happening to our lives through the internet via the likes of Google, Salesforce.com, Microsoft and Google and so on.
"The Big Switch provides a panoramic view of the new world being conjured from the circuits of the "The World Wide Computer"."
Now, doesn't that sound very promising? Geert Lovink has a detailed post.
