Mrs. S is Sarah and Felix’s duplicitous foster mother. A mother hen figure whose compassion is matched only by the “hard love” she dishes out, Mrs. S has also been the caretaker of Sarah’s daughter Kira. Her sole focus was keeping Kira safe from the wild ways and questionable acquaintances of her rebellious mother. But Sarah’s newfound family has caused Mrs. S to make decisions to protect Sarah and Kira: trading Helena to Paul and his military network in order to spare them. Remaining connected to an underground organization of activists who don’t shy away from violence when necessary, Mrs. S will need all the help she can get when Sarah finds out what she’s done. What will the ramifications of her decisions mean for the family she’s fought to protect for over 20 years?
