William Kent Krueger offers "one of his most puzzling mysteries to date" (Publishers Weekly) as a disappearance and a dead body put Cork O'Connor's family in the crosshairs of a killer in the twentieth book in the New York Times bestselling series.

The disappearance of a local politician's teenage daughter is major news in Minnesota. As a huge manhunt is launched to find her, Cork O'Connor's grandson stumbles across the shallow grave of a young Ojibwe woman--but nobody seems that interested. Nobody, that is, except Cork and the newly formed Iron Lake Ojibwe Tribal Police.

As Cork and the tribal officers dig into the circumstances of this mysterious and grim discovery, they uncover a connection to the missing teenager. And soon, it's clear that Cork's grandson is in danger of being the killer's next victim in this white-knuckled mystery from "a master storyteller at the top of his game" (Kristin Hannah, #1 New York Times bestselling author).
