A suspected suicide in Dublin. A brutal murder in New York. The abduction of a child over two decades earlier. All linked ... but how? Criminal psychologist Dr Kate Pearson has the answer. Because she was the young girl abducted all those years ago. And, when she begins to investigate the suspicious suicide in Dublin and confirms a connection to her own disappearance, she is forced to start asking questions. Why did her parents lie to her, telling her she was missing for only a few hours? And why doesn't she have any memory of the time she was held? When a sinister note arrives at her home, it becomes clear that Kate is being targeted. But by whom? And why now? Kate is consumed by her efforts to uncover the truth, knowing that her life is in very real danger. The Game Changer wants someone to pay for the past - and Kate is being held accountable.
