Twenty years ago this October, Rebecca Solnit was writing about the Kennedy assassination for her first book when the Loma Prieta earthquake struck. She hit save, stood in a doorway until the shaking was over, and marveled in the days after at the calm, warm mood of the people of her city and her own changed state of mind. She’s written regularly for TomDispatch since the outbreak of the war in Iraq. Her just published new book, A Paradise Built in Hell(Penguin, 2009), is a monument to human bravery and innovation during disasters.
