Picoult brings to life a female prosecutor whose cherished family is shattered when she learns that her five-year-old son has been sexually abused.

What does it mean to be a good mother?

How far would you go in the name of love—and justice?

In the course of her everyday work, career-driven assistant district attorney Nina Frost prosecutes child molesters and works determinedly to ensure that a legal system with too many loopholes keeps these criminals behind bars. But when her own five-year-old son, Nathaniel, is traumatized by a sexual assault, Nina and her husband, Caleb, a quiet and methodical stone mason, are shattered, ripped apart by an enraging sense of helplessness in the face of a futile justice system that Nina knows all too well. In a heartbeat, Nina's absolute truths and convictions are turned upside down, and she hurtles toward a plan to exact her own justice for her son—no matter the consequence, whatever the sacrifice.
