Anger is a natural emotion to perceived injustice, and most of us succumb to it from time to time and then get over it. Unrestrained anger is another matter, for it often leads to rage which casts a wide shadow on its victims.

The heroine's reaction is a learned response based on a history of violence. She has a hard time distinguishing between anger and rage, and has no coping skills other than to run. As the story progresses, this amplified response leaves her vulnerable as she struggles to find coping skills that will protect her adult relationships.
