Fourteen-year-old Mimi does not just love her two elder sisters, she worships them: the beautiful, cosmopolitan Deïna with her enveloping tenderness and the cool, inscrutable Astrid who believes she could not live without Deïna. Mimi's world is in order as long as the three sisters are together, as long as they do things together, discuss everything and share everything: their childhood, the family rituals, even their anger at their mother Marga who, amusing, tyrannical and full of vitality, has her own very definite ideas about her daughters. The harmony among the three sisters is stronger even than delicate and important issues such as the first balls, the first parties, the first admirers… Until someone comes along whose love they cannot share. Mimi foresees the catastrophe, but she is paralysed by the dilemma of not knowing which sister to support. She is traumatised by the fact that those who used to love each other have become deadly enemies, and that she cannot comfort or reconcile them. For half a lifetime.
