Everyone loves the Wizard of Oz! Geoff Ryman returns us to childhood, the time when the distinction between art and reality was not so clear. He reminds of the time when seeing a movie like the Wizard of Oz was so powerful that it changed our lives, by crawling up into our tiny heads and never coming down. The Wizard of Oz and films like it are to our culture what the Ramayana is to India; it is a narrative shared by the whole culture together, an epic, a source of references that can lead to mutual understanding, an art form that endlessly gives rise to more and more beautiful art. What is in this book? The true, tragic story of Dorothy; real Munchkins and their make-up artist; a man trying to complete a pilgrimage to the sacred sites of Ozism before the disease he carries kills him. Geoff Ryman writes like a delirious angel. I read this book more than three years ago and it still haunts me.
