Originally published in 1977, Do What They Say or Else is the second novel by French author Annie Ernaux. Set in a small town in Normandy, France, the novel tells the story of a fifteen-year-old girl named Anne, who lives with her working-class parents. The story, which takes place during the summer and fall of Anne's transition from middle school to high school, is narrated in a stream-of-consciousness style from her point of view. Ernaux captures Anne's adolescent voice, through which she expresses her keen observations in a highly colloquial style.

As the novel progresses, and Anne's feelings about her parents, her education, and her sexual encounters evolve, she grows into a more mature but also more conflicted and unhappy character, leaving behind the innocence of her middle school years. Not only must she navigate the often-confusing signals she receives from boys, but she also finds herself moving further and further away from her parents as she surpasses their educational level and worldview.
