Sophie is Grace’s smart seventeen-year-old half sister. She is almost too smart for her own good in the world she lives in. She dreams of going to college and doing something with her life that she finds fulfilling. Instead, her father has decided that she will marry someone who will increase the family’s success and notoriety in the world. She wants nothing to do with that. What she wants is to change the world. While she’s only ever known the Reich, she believes there is a better life without them. Her best friend, Will and herself, discover a family secret of Will’s grandfather, George. Not only is Will adopted, but he’s also Jewish, a fact seemingly impossible given the Nazi extermination of Jews decades earlier. She has more determination than the grownups around her and gets caught up with the FFA. At first she does smaller things, like producing leaflets denouncing the Party, many of the information she gets while researching her senior year history project at the restricted section of the National Archives where, Grace, works. She eventually risks her life by participating in high-level actions intended to harm and ultimately destroy the Reich. While she becomes an eager participant in the resistance against the Party, her father and the rest of her family still believes she is a role model for other girls her age.
