1636: Commander Cantrell in the West Indies was released in June 2014, and is my latest contribution to the 1632 universe.
Eddie Cantrell, now married to the king of Denmark’s daughter, is sent by Admiral Simpson to the Caribbean to secure access to the most valuable commodity on that continent—not the gold and silver which the Spanish treasure, but the oil which up‑time machines and industry need. The admiral has also provided Eddie’s small task force with the new steam-powered frigates that have just come out of the navy’s shipyards.
