After escaping a death sentence in the summer of 1775, Octavian and his tutor find shelter but no safe harbor in British-occupied Boston and, persuaded by Lord Dunmore's proclamation offering freedom to slaves who join his counterrevolutionary Royal Ethiopian Regiment, Octavian and his friends soon find themselves engaged in naval raids on the Virginia coastline as the Revolutionary War breaks out in full force.

Various diaries, letters, and other manuscripts chronicle the experiences of Octavian, a young African American, from birth to age sixteen, as he is brought up as part of a science experiment in the years leading up to and during the Revolutionary War.
