In Etheca, each and every person lives a full life. All diseases and illnesses have been eradicated, and there are no more genetic defects or abnormalities which impede on the quality of life. All resources are shared equally amongst all people and every phase of life is catered for to ensure that each human being lasts for their designated 125 years. When one's time on Earth has been exhausted, their body is surrendered to harvest new life. When an infant is grown from the deceased, it supplants its lifegiver and is sterilised to maintain the order of the population. Within this society lineage and genealogy are of no importance; gender has been removed from sex, and from sex the production of human life. Pip was created in Etheca twenty-eight years ago. She is an only child to her two caregivers and has no plans to be one herself. She has trained her whole life to become a leading libera at the Menkin centre, with the hope that she can study the wakers who have established life in Hera, a municipality beyond Etheca. Pip and her team set out on their assignment, and discover that wakers willingly reject medical intervention; their society is rife with sickness and premature death. They meet Eve, a teenage girl desperate to flee Hera, who reveals to Pip and her auxiliary libera, Don, that she is growing a child and will soon undergo a dangerous biological process called birth. Pip is determined to not only save this girl, but to investigate the possibilities she can bring to improve the quality of life in Hera. Unbeknownst to Pip, Don begins to obsess over this new-found understanding of birth, endeavouring to uncover the very genesis of humankind, a notion which threatens to dismantle all of Etheca.
