Kay Malloy always knew hers would be a life of service. Following the tragic death of her humanitarian parents, Kay and her brother, Christopher, were raised in a world of wealth and culture by their godparents. With ambition and selflessness, Kay joins the FBI to honor her parent's legacy, even while Christopher's life grows increasingly aimless. Paramilitary and male-dominated, the FBI could be an intimidating employer to anyone less confident, devoted, and insightful than Kay. But after early success in the Violent Crime Program in Baltimore she struggles working counterintelligence in New York. When Kay is assigned to investigate the loss of Russian government double agents, she sees this as her chance to prove herself. As pressure mounts and conflicting leads cloud the investigation, Kay discovers she must make the impossible choice between those she loves and the country she's sworn to protect.
