The sea does not keep secrets.

In Sea of Nations, the sixth sweeping novel in Gideon Mercer's Keepers of the Way series, the mission leaves the roads of Antioch and enters the dangerous harbors of Cyprus-where rumor travels faster than truth, one stolen packet can expose an entire network, and a single wrong name at the wrong gate can turn faithful houses into targets.

As Mattai ben Azariah, Barnabas, Paul, John Mark, and Yosef press into Salamis, they discover that the work of carrying the message of Jesus across the ancient world is no longer only a matter of courage. It is now a matter of hidden routes, guarded doors, divided loyalties, and men who know how to read weakness before it is spoken aloud.

In a city shaped by trade, suspicion, and the restless traffic of nations, the word begins to spread through synagogues, courtyards, harbor lanes, and upper rooms filled with secrecy and hunger. But every new hearer brings new danger. A missing packet. A tested phrase. A smiling scribe asking the wrong questions. And behind it all, the growing realization that the gospel is moving faster than any one man can protect it.

Rich with first-century tension, spiritual conviction, and historical atmosphere, Sea of Nations is a powerful biblical historical adventure about costly obedience, fragile trust, and the peril of carrying truth through a world already reaching to seize it.
