The setting is Castine, a small port village on Penobscot Bay in what is now the state of Maine. As the storm clouds portending the Revolutionary War grow in ferocity, the dangers that the citizens of Castine live with daily intensity- skirmishes with the fierce Abenaki Indians, piracy in the waters off their bay, and the harshness of the North Atlantic elements. A trader along the easter Seaboard, Captain Matthew Jarden has carefully avoided trouble in his years of plying the sea- this despite strident opposition to the slave trade. But when a British-Indian alliance lays siege to Castine, just days after the death of his beloved wife, the proud captain becomes a hunted man with a bounty on his head. The only place more dangerous than Castine is his ship, and so reluctantly he smuggles his only daughter, Rosea, shore, knowing too well the dangers that await her. Nightsong is the story of Rosa Jarden's courageous fight to survive, to do what is right before God, to be a part of the birth of a great nation. Based on a Revolutionary War events that occurred in and around Castine Maine.
