"I am convinced of the moral urgency that there is to get down to imagining together a different education for our children, in an attempt to create a more just world with regard to women and men." To a friend who asks her for some advice on how to raise the little girl she has just given birth according to the rules of the art of feminism, Chimamanda Ngozi Adichie responds in the form of a cheerful missive, not devoid of irony, which quickly took the form of a manifesto. The Nigerian writer examines the concrete situations that arise for the parents of a little girl and explains how to overcome the traps that sexism sets for us, through examples drawn from his own experience. This manifest letter is addressed to everyone: to men and women, to parents in the making, to the child who subsists in us and who wonders about the education he has received. Everyone will find the keys to a feminist line of conduct, which consists in believing in full equality of the sexes and in encouraging it.
