Growing up in 1930s Brooklyn, Florence Fein will do anything to escape the confining values of her family and her city, and create a life of meaning and consequence. When a new job and a love affair lead her to Moscow, she doesn't think twice about abandoning America - only to discover, years later, that America has abandoned her. Now, as her son Julian travels back to Moscow - entrusted to stitch together a murky transcontinental oil deal - he must dig into Florence's past to discover who his mother really was and what she became.
