People began predicting the exact time of their own deaths. And then they died exactly when they said they would. No threats. No violence. No supernatural forces. When former criminal psychologist Edward Hale is called in, he discovers something far more disturbing than prophecy. Someone is giving people certainty - and that's all it takes. A psychological detective mystery about influence, belief, and how easily the human mind can be guided toward an ending. Calm. Intelligent. Unsettling.
