Martha Quest, a young woman with a complex personality and various almost childish, barely controlled defence mechanisms in place, flees the South Africa she grew up in to find a new life in post war Britain.
The change from the hedonistic society she knew to the apathy she finds there makes adaptation seem impossible. She is hounded by friends of her family who cannot understand why she won't take a boring office job, or join in their circle which epitomises her life before.
She at last finds a strange job helping an author tidy up his manuscript, and from here gets absorbed into his complex extended family. During the years of the novel this family grows and evolves, the members mature; and Marta's role as mediator super partes puts her in a complicated position of impotent power with responsabilities she would rather not have.
The elder relations still try to influence public life as they did before the war, with parties and meetings. The younger ones seem completely out of touch, becoming whizz kids or drop-outs.
The evolution of the political world, adapting new comunication technologies to their power play, wrong foots the family who lose the grip they thought their birthright. The country slides towards some ill defined catastrophe as the politicians' spin loses contact with reality.
Martha escapes with a number of members of the family to a remote island, where they manage to scrape a living. The dramatic denouement is not mere survival, but the preciousness of abilities that some members of the family had already had, and which had caused them to be institutionalised, in the 50's and 60's.
Lessing's prose handles the intricazies of these relationships with clarity and compassion, her tale seems prophetic, not only of the vices of today's political world but of a man-made catastrophe that we will perhaps face in the near future.
