After The Silence by Louise O'Neill

On a remote Irish island, a glamorous couple’s party ends in the death of a young woman, a crime that remains unsolved for a decade. When a true-crime documentary crew arrives to reexamine the case, old resentments and buried secrets resurface, revealing a web of coercive control, gaslighting, and communal complicity. As interviews and memories collide, a woman is forced to confront the truth about her marriage and the night that forever changed the island.
