What readings change your view of the future?

I read this post about a new book, "Threats in the Age of Obama" (http://www.typepad.com/services/trackback/6a00d83451b06369e2010536fae90f970c)

One of the authors writes:  " Whatever you may have thought the next decade may bring before reading this, I guarantee you will be challenged to think about it differently, more holistically and in more depth afterward."
