Following the development of massive airships, naive Londoner Bert Smallways becomes accidentally involved in a German plot to invade America by air and reduce New York to rubble. But although bombers devastate the city, they cannot overwhelm the coutnry, and their attack leads not to victory but to the beginning of a new and horrific age for humanity. And so dawns the era of Total War, in which brutal aerial bombardments reduce the great cultures of the twentieth century to nothing. As civilization collapses around Smallways, now stranded in a ruined America, he clings to only one home - that he might return to London and marry the woman he loves.
