Buenos Aires, the 1970s. Julia inherits from her grandmother a gift, precious and burdensome. Sometimes visions appear before her eyes, mysterious and terrible apparitions from the future, seen from the perspective of others. From the age of five, Julia must intervene to prevent horrific events. In fact, as her grandmother tells her, it is her duty to do so—otherwise she will lose her gift. 

At fifteen, Julia falls in love with Theo, a handsome revolutionary four years her senior. Their lives are turned upside down when Juan Perón, the former president and military dictator, returns to Argentina. Confronted by the realities of military dictatorship, Julia and Theo become Montoneros sympathizers and radical idealists, equally fascinated by Jesus Christ and Che Guevara. Captured by death squadrons, they somehow manage to escape. . . .

In this remarkable novel, Betancourt, an activist who spent more than six years held hostage by the FARC in the depths of Colombian jungle, returns to many of the themes of Even Silence Has an End. The Blue Line is a story centered on the consequences of oppression, collective subservience, and individual courage, and, most of all, the notion that belief in the future of humanity is an act of faith most beautiful and deserving.
