Between 1739 and 1748, Britain is locked in a brutal struggle for empire; its fleets battling the Spanish and French across the Caribbean, the Americas, and beyond. Into this deadly contest sails Edward Mainwaring.

Born in Massachusetts but serving as a lieutenant in the Royal Navy, Mainwaring is an outsider - a Royal Yankee - caught between worlds. In 1739, he and the crew of his swift Bermudan schooner Athena find themselves in the Caribbean, poised to join Vice-Admiral Vernon’s daring assault on the heavily fortified Spanish stronghold of Porto Bello.

As cannon fire thunders and empires collide, Mainwaring must prove himself in battle, outwit a relentless French adversary, Roche-Bourbon, and challenge for the love of the beautiful Anne Brixham - a fighting planter's daughter and a match for most men.

From desperate naval engagements to high-stakes intrigue and perilous missions, Royal Yankee is a gripping tale of courage, rivalry, and leadership under fire.
