Philip K Dick's acclaimed cult novel gives us a horrifying glimpse of an alternative world - one where the Allies have lost the Second World War. In this nightmare dystopia the Nazis have taken over New York, the Japanese control California and the African continent is virtually wiped out. In a neutral buffer zone that divides the rival superpowers in America lives the author of an underground bestseller. His book offers a new vision of reality, giving hope to the disenchanted. Can other, better worlds really exist?
