Unknown Connections is a compelling saga of men struggling to preserve the freedom of their respective countries that spans seven generations and the entire 20^th century. After their parents are butchered in a pogrom in 1905, Isaac and Noah Shmurak leave Russia. The brothers abandon their religion and their names to establish new lives in new lands. Although they never meet again, the lives of their descendants are strangely parallel, although in different countries. Follow these families through the triumphs and tragedies of the Russian Revolution, World Wars I and II, and the Cold War. How does the Shmurak legacy climax in the development of the Russian and American submarine forces, and what is the meaning of a photograph of a Jewish bride and groom taken in 1880 have for two admirals: one Russian and one American? Unknown Connections weaves a rich tapestry of history, adventure, and once-classified naval technology to bring the saga to its exciting conclusion.
