Four missing girls. Four daughters cruelly torn from their parents. Four families torn apart, united by the same cry: justice and answers. The Fens, England. The battered body of a young woman appears on a remote and desolate beach on the North Sea, plunging the community into a spiral of fear and uncertainty. Shortly afterwards, a troubled teenager named Toni is found wandering, disoriented and covered in mud, in the thick fog of the Fenland wetlands. In a deep delirium, the young woman repeats the name Emily over and over again. She says she met her at a secret party they both attended and claims to have seen someone take her away by force. In light of these findings, the echoes of a case relegated to oblivion resurface: the disappearance, ten years earlier, of a girl whose whereabouts remain a mystery. Her mother, devastated by grief, demands that the police reopen the investigation. Once again, Detective Rowan Jackman and Sergeant Marie Evans find themselves caught up in a web of secrets and danger, where nothing is as it seems. On the trail of a group of men who run an underground club where alcohol, drugs, and child abuse run rampant, their investigations lead them to Windrush, an old abandoned sanatorium whose walls hide unimaginable horrors. The Lost Daughters is a gripping, tension-filled thriller where innocence is pitted against the most inhuman brutality and corruption. With every unexpected twist, the novel unfolds a dark reflection on loss, guilt, and the struggle for justice in a world where the shadows of evil lurk closer than we think.
