"There is no one who can surpass the expert knowledge of Kathy Reichs..."
A young girl murdered in Vermont is linked to another case years later in Carolina. Tempe Brennan is called in as DNA points to the perpetrator being one Anique Pomerlau, a very unpleasant reminder from the past of one of Brennan's cases that was never satisfactorily concluded. When another young girl goes missing, Tempe has to find her erstwhile colleague and lover, Andrew Ryan who has taken leave of absence to recover from the tragic death of his daughter.
Together, as they tentatively renew their working relationship, they track down what has happened to Pomerlau, who seems to be taunting Brennan with her inability to close in on her. But it is not as simple as finding Pomerlau. The evil acts she committed cast long shadows and it is only dedicated policing and inspired research that finally stops the trail of devastation she began.
