In the final days of World War II, an Irish soldier discovers a cache of artifacts in an Austrian cave that threatens to expose long-buried secrets of the Catholic Church. Secrets that prove the Druids of Ireland did not die out; they were systematically exterminated in cold blood. However, the secret will stay buried within the walls of the soldier’s home for another fifty years before it is brought to light by his son, a modern-day proponent of the Druids’ enlightened, pacifist culture.

Armed with the evidence and the conviction to expose the Church’s conspiracy, the soldier’s son, a Supreme Court justice, forms an unlikely alliance with a healer, a linguist, and a Boston attorney to bring the Vatican to trial. As the action races from the corridors of the White House and the United States Supreme Court to Dublin’s halls of academia and the secretive back passages in Rome, the Church will stop at nothing to silence the voices of the past.
