Imperative Birth is part three of three books where two television journalists interview 100-year old Jonara Pindus, the mother of female-couple fertility, to discover what led Jonara to her profession. Jonara completes the story from her thirteenth birthday when she goes back in time. She witnesses 13th century Spain, the male-mammal extinction on distant planet Eho Miriam, the recovery of her young mother's psyche, the origins of her mother's conception, and a multiple coming-together of events for the finale.
