If I had to pick the one best book I've read in 2009, it would be
The Shock Doctrine: The Rise of Disaster Capitalism by Naomi Klein. It’s the story of how the I-got-mine-screw-the rest-of-the-world-crowd gets richer while the middle class shrinks and the poor get shafted. It's the most important book I've read this year.
Number two on the list is
The Evolution of God by Robert Wright. In a world where the heirs of Abraham are apparently ready to cut each other's throats at a moment's notice, this book presents hope for the future, and explains why tolerance and cosmopolitanism is in God’s best long-term interest.
