The search for a missing baby unmasks a sadistic killer... Lucy Guardino has fought and defeated evil before... but nothing like the case Dr. Cassandra Hart brings to the Beacon Falls team: a missing infant, his mother dead. Alina, was only nineteen, full of hope—despite being raped, left for dead, and finding herself pregnant with the rapist's child. Then Alina kills herself. The world thinks she also killed her newborn baby. No one will investigate further, not without forensic evidence. No one believes there is a link between Alina's case and the brutal murders of other women. No one except Dr. Cassandra Hart and former FBI Special Agent Lucy Guardino. Two women, both fiercely passionate about justice for the victims they serve. And both just as determined to defeat the evil stalking the streets of Pittsburgh... even if it means risking everything. But when justice fails them, where will they draw the line? Is there ever a time when taking the law into their own hands is the Lesser Evil?
