Ada grows up motherless in the Jewish pogroms of a Ukrainian city in the early years of the twentieth century. In the same city, Harry Sinner, the cosseted son of a city financier, belongs to a very different world. Eventually, in search of a brighter future, Ada moves to Paris and makes a living painting scenes from the world she has left behind. Harry Sinner also comes to Paris to mingle in exclusive circles, until one day he buys two paintings which remind him of his past and the course of Ada's life changes once more.
But then recession and revolutions shake previously rich regimes. As summer draws to a close, Ada's world is disintegrating, and she is faced with a fateful decision.
