Karma has endured twenty-five years underneath the earth. Her path in life—a path she never bargained for—has included marriage to a man she never chose, whose powerful position forces her to hide her memories of the time before. On the day her son takes as his bride a girl from the Down Deep, an explosion resounds throughout the Silo. Is the anger and frustration of the people spilling over to the long-feared uprising? As the toxic view of the Outside still lurks on the wallscreen, and the inside erupts in ever more violence, Karma must strike out to protect her family.
