Emma is the story’s protagonist and, as it begins she’s 21 years old. Small and dark, she has strong facial features and a serious manner. Emma’s childhood was difficult since she suffered constant verbal abuse from her father, who wanted a son. These early experiences of hardship strengthen her resolve to prove herself just and strong and capable as any man.

After fleeing her home in Canada, Emma dresses as a man to escape capture. She comes to realize that this disguise allows her to escape the limited role that society has assigned her as a girl. Passing as a man makes it possible for Emma to enlist in the army. Her dexterity with hiding her gender soon evolves into a talent for creating multiple disguises that she employs as a spy. Emma’s cool-headed courage in spying behind enemy lines earns her the respect of her fellow soldiers and an honored place in Civil War history.
