An empire has collapsed from boredom and loss of faith in itself. In the Emergency that follows, youth rebellions of urban Burghers and rural Yeomen embrace radical new ideas of humanity. Doctor Hugo Rustin, chief surgeon at the Imperial College Hospital, is increasingly estranged from his city and his family --- from his wife, Annabelle, who finds fulfillment in their changed community; and especially from his teenage daughter, Selva, who has turned against her father’s values. When an incident at the hospital leads to Rustin’s disgrace, he seeks redemption in a quixotic and dangerous journey into the countryside, with Selva as his companion, just as the conflict between Burghers and Yeomen is reaching a crisis.
