After narrowly avoiding death in London at the hands of the king's secret agents, Duncan McCallum returns to colonial America only to discover that his troubles have followed him across the Atlantic. The harbour town of Marblehead, Massachusetts, is a smoldering powder keg as British loyalists and advocates for liberty feverishly maneuver to determine the future of the colonies. When a Native American sailor is scapegoated for the gruesome murders of officers of the British occupation troops, McCallum will have to face off against ruthless adversaries close to the crown. Soliciting the assistance of such notable historical figures as John Hancock, Crispus Attucks, and John and Samuel Adams, McCallum must rely on his skills in science, subterfuge, and diplomacy to stave off a war for which America is not yet prepared. Just as Patrick O'Brian's Master and Commander series took readers on a thrilling journey through the Napoleonic Wars, Freedom's Ghost and the Bone Rattler series offer riveting historical adventures embedding readers in the clashes and intrigue of the American Revolution.
