As the war rages on in the summer of 1943, causing massive destruction and widespread fear, the King and Queen choose to quietly send their youngest daughter, Princess Charlotte, to live with a trusted noble family in the country. Despite her fiery, headstrong nature, the princess's fragile health poses far too great a risk for her to remain in war-torn London. Third in line for the throne, seventeen year-old Charlotte reluctantly uses an alias upon her arrival in Yorkshire, her two guardians the only keepers of her true identity. In time, she settles comfortably into a life out of the spotlight, befriending a young evacuee and training with her cherished horse. But no one predicts that in the coming months she will fall deeply in love with her protectors' son.
