In 1865, America is a nation ravaged by four years of Civil War. Bess discovers that among the Irish-American Fenians money and power and patriotism are entangled in bewildering and demoralizing ways, while Dan McCaffrey surrenders to the corruption of New York City politics. The Fenians' invasion of Canada and their goal of holding the English colony hostage for a free Ireland become a hot issue in a power struggle between Democrats and Republicans. When the American federal government double-crosses the Fenians, forcing thousands of Irish Civil War veterans to abandon the Canadian invasion after winning the first battle, acrimony engulfs the movement, leading to feuds, name-calling--and murder.
