Divergent

Natalie Prior, Tris and Caleb’s mother, was the daughter of a Dauntless leader and Divergent herself, but her mother warned her that people were searching for Divergents and she needed to escape, so she moved to Abnegation to begin a new life. Though she appears nothing but selfless and kindhearted, she has an inner core of strength that is revealed to Tris at the end of the novel.
