Les Particules élémentaires: 2009. Michel Djerzinski, a genius researcher specialized in molecular biology, mysteriously disappears in Ireland. His latest discoveries would have opened the way to a major upheaval in the history of human genetics. This is the occasion for a dizzying plunge in time where we discover his half-brother Bruno, a tortured joker who will meet love in a post-sixties campsite, Janine, Bruno's and Michel's mother, a former hippie who has always refused to raise her children in a conventional way, and Annabelle, with whom Michel will fall in love as a child.
