El títol daquest penúltim llibre de lautor britànic Ian McEwan fa referència a The Children Act 1989, un acte amb el qual el parlament anglès defineix les funcions atribuïdes a les entitats locals, als tribunals, als pares i a les agències del Regne Unit per garantir i promoure el benestar dels menors. El jutge Maye senfronta al cas dAdam Henry, un noi de 17 anys que, ajudat per la comunitat de Testimonis de Jehovà de la que forma part, no accepta una transfusió de sang que podria salvar-li la vida.
Fiona Maye is a leading High Court judge, presiding over cases in the family court. She is renowned for her fierce intelligence, exactitude and sensitivity. But her professional success belies private sorrow and domestic strife. There is the lingering regret of her childlessness, and now, her marriage of thirty years is in crisis.
At the same time, she is called on to try an urgent case: for religious reasons, a beautiful seventeen-year-old boy, Adam, is refusing the medical treatment that could save his life, and his devout parents share his wishes. Time is running out. Should the secular court overrule sincerely held faith? In the course of reaching a decision Fiona visits Adam in hospital - an encounter which stirs long-buried feelings in her and powerful new emotions in the boy. Her judgment has momentous consequences for them both.
