For almost forty years, Fr Sean McManus has been at the heart of the Irish American campaign to pressurise the British government regarding injustice in Northern Ireland. This is a deeply personal account of how his lone voice mainstreamed Northern Ireland on Capitol Hill, after the Catholic Church removed him from Britain. He became 'Britain's nemesis in America', founding the Irish National Caucus in 1974. Also chronicles the events and social context that influenced him, growing up in a parish divided by the Border.
