How Algebra Rejoined the Broken Pieces

A young girl searches for her parents, who left her at three years old, for reasons unknown to her. Brought up by various relatives, she decides on a quest to find them, so following various clues, her search takes her from Russia to Jazz Age New York.
Set against the 1920s, the young woman now in her twenties, her search concluded and her parents found, settles into New York life with her new found friends. Her life is enriched by all she meets, and the experiences she has, including the Wedding of Mary and Robert, and the meeting and 'walking out' with one of the rising stars of the New York Yankees baseball team.
A most enjoyable life marred only by the intervention of the Bureau of Investigation, constantly checking her papers, in their search for what, she is not really sure.
A story resolved, or is it?
