In the affluent beachside town of Pirriwee, on the edge of Sydney, three mothers with children starting kindergarten find their lives quietly colliding. Madeline is sharp-tongued, loyal, and still nursing old grievances; Celeste is beautiful, wealthy, and privately unravelling; and Jane, a young single mother new to town, carries a secret about her son's father that she has told no one.
From its opening pages the novel makes clear that a parents' trivia night at the school will end in a death — but not who died, or how. Liane Moriarty works backward and forward around that night, unspooling months of playground rivalries, misunderstood accusations, and the small daily performances that hold a marriage or a friendship together.
Beneath the wit and the suburban comedy runs a serious study of domestic violence, shame, and the way communities close ranks around uncomfortable truths. Told through multiple points of view and interspersed with gossip from the other parents, Big Little Lies builds steadily toward a reveal that reframes everything, while staying rooted in the ordinary texture of school runs, coffee mornings, and second marriages.
