A desperate plea to save a dying son draws Rangers Baker and Tate into Harvest Home — a town frozen in time, sealed off from the outside world, where medicine has been replaced by rituals and children are taken for ceremonies no one dares resist. What starts as a rescue turns into a fight for survival in a town that tightens like a noose.

A derailment exposes a trafficking pipeline that has been moving human cargo through the heartland for years — and another train departs in hours, carrying children who will disappear forever if it reaches its destination. Ruth boards it, and now she and Aaron are trapped on a speeding train full of killers where there are no scheduled stops, only scheduled deaths.

He takes them quietly, one by one, and keeps them somewhere no search has ever reached. Katie Ford races to find the place before the next name on his list becomes hers.
