In 9 Rules of Engagement, Harris uses her father’s stories, his career, and the profound father-daughter bond they’ve shared throughout her life to explore nine life lessons—each rooted in military life—that have shaped her career and molded her as a person. Whether discussing how to “devise your mission,” “stay ready,” or “think like a general,” these rules reflect a lifetime spent absorbing the military mind-set for success, while always keeping one foot in the civilian world. Examining the courage, determination, and patriotism that her father’s service has inspired in her, Harris shows how his stories of combat and responsibility have been an essential ingredient in her rise through the ranks of national broadcasting, guiding her to her goals regardless of the circumstances. Along the way she interviews other military families, generals, and former and active service members now serving in the United States Congress to illuminate why the message and mission of the military is so effective at changing lives both on and off the battlefield.
