In the nineties, Meritxell is a successful writer. She has written countless stories, but has never managed to unravel the one that really matters to her: that of her own origins. She knows that her mother was Parisian and her father was a Civil War fighter, but she never got to know him.

In the 1940s, in Nazi-occupied Paris, Anne-Marie lives in the Le Marais district. In the small boarding house run by her parents, Armand arrives; it seems that he is hiding from the German invaders because he is fleeing from a work camp. In a Paris that is fighting underground, the young Anne-Marie will learn about the strength of first love and what it means to have convictions.

A novel full of tenderness that links two periods and shows us how important personal roots are. Characters who embody the strength of ideals and portray anonymous people who overcame fear to fight the monster of fascism.
