About This Book

Some relationships resist easy categories—and few are more fraught than the one between a woman and her mother-in-law. Lucy has spent years trying to crack Diana's polished, impenetrable exterior, desperate for warmth that never quite arrives. When Diana turns up dead, the suicide note doesn't hold up, and suddenly Lucy finds herself at the center of something far darker than a difficult family dynamic. Sally Hepworth takes the quiet tension of a strained family bond and turns it into something genuinely unsettling, asking how well we ever really know the people we're supposed to love—and whether our own version of events is the one that actually matters.

What makes this novel particularly rewarding is its dual-timeline structure, which alternates between Diana's and Lucy's perspectives across years of accumulated misunderstanding. Hepworth writes the gap between intention and perception with real precision—Diana is never simply a villain, and Lucy is never simply a victim. The prose is controlled and domestic on the surface, with something colder underneath, which suits the material perfectly. It's the kind of book where the last chapters reframe everything that came before.
