A thirty-something teacher drifts through her life in Paris, raising a daughter on her own, lonely in spite of a new boyfriend. Then one night, at a friend’s tepid New Year’s Eve party, Sarah enters the scene like a tornado. A talented young violinist, she is loud, vivacious, appealingly unkempt in a world where everyone seems preoccupied with being ‘just so’. It is the beginning of an intense relationship, tender and violent, that will upend both women’s lives.
