Marina Kamenev’s Kin begins with a calmly unadorned outline of the nuclear family’s recent fortunes. In the space of just a few pages, she gives a condensed tour of the concept’s history, concluding with US historian Stephanie Coontz’s suggestion that the nuclear family is a ‘historical fluke’ – one that has, as Kamenev puts it, ‘been idolised long after its use-by date’. The introduction’s mini-tour prefigures, in capsule form, both the book’s thematic emphases and its guiding rhetorical procedures. As Kin’s chapters move through their discussions of the moral panics that accompany non-nuclear family structures, from same-sex parenthood to chosen childlessness to single-parent families, the book reveals that the real moral hazards of reproductive technology lie not in deviations from the nuclear model but in attempts to impose the model where it doesn’t fit.
