A brave, not too historical adventure story of two youths in the turbulent and of the 1th century, clock and sword merged into stalwart Americana. Jonathan Brewster, straight New England skipper, rescues the reputedly legitimate son of Charles Edward, the Young Pretender, from the River Loire. They sail for San Domingo to rescue a French vicomtesse from a slave revolt -- and then on to American and the Canadian frontier. Jaite Jacobite Inntrigue (whence the title of the book) brings tragedy in its wake, but romance links Jonathan and his French girl. Well-written, colorful, but at times it seems a bit overlong.
