A curious priest uncovers a mystifying secret... One that leads to a long-buried relic some will do anything to possess. Can he outwit adversaries who will stop at nothing to keep him from revealing an object that challenges history as we know it? Father Michael Dominic discovers a strangely constructed 13th-century puzzle hidden deep within the Vatican Secret Archives. With the help of his brilliant colleague, investigative journalist Hana Sinclair, solving the puzzle exposes a cleverly concealed map that marks the hiding place of a sacred artifact-one with shocking implications. From Rome to France and Switzerland, his search for the object finds Dominic pitted against deadly agents and a ruthless Russian oligarch. Desperate, he must choose between trusting an unlikely collection of possible allies-or certain death. As his enemies close in, can he survive and bring this staggering new secret to light, or will his pursuers bury it beside him in the cold, dark earth of a long-forgotten cave?
