I haven't seen anyone announcing this, so I thought I'll just drop a note:
Published in a hardcover by the University of California Press, Storming the Gates of Paradise: Landscapes for Politics collects more than 40 essays across her career, and deals with her insights into culture, social politics and environmental concern. It is more politically motivated than Wanderlust and A Field Guide To Getting Lost, but yet totally coherent with her entire life's work. Her writing has always been about staying engaged with the world we live in, opening our hearts and minds to the infinite curiosities of everyday life and acting conscientiously. Afterall, this woman wrote an entire book on the ordinary everyday act of walking and made it profound and romantic.
