A mysterious stranger holds the key to the fate of the nation. In the final days of the American Revolutionary War, Nessa Shaw tends to the sick and wounded at the Continental Army camp in Charlestown, South Carolina. When she stumbles upon a man lying unconscious on a forest trail, she quickly realizes he is unlike any patient she has ever encountered. With no memory of his past, his only clues to his identity are his first name-August-and the certainty that he is a Patriot. Against her better judgment, Nessa grows closer to August, trusting him with secrets that could cost her dearly. But when she discovers a deadly plot that could change the course of the war, Nessa must question everything she thought she knew about August and his true allegiances.
