Somewhere in the Pacific, 1943. Kate Campbell is a nurse who bravely flies back and forth from the front to rescue wounded soldiers, amid long days, harsh conditions and often dangerous weather. Driven by a deep personal need to help in the war effort, she is disappointed when an accident leaves her injured and sends her home to New York.

By the time she's healed, the war has moved on, and rather than being returned to her post in the Pacific, Kate is sent to the English countryside. There, Kate comes face-to-face with the enemy and confronts the heavy toll of violence while tending to the soldiers in her care. She never intended to fall in love, but despite herself, she falls for an officer with a broken femur, startling blue eyes and a wicked sense of humor.

For the first time, Kate sees a future for herself. But before she can pursue it, a secret from her past calls her to duty, and she'll have to travel back into danger one more time to rescue a part of herself she'd left behind. But will she make it back? And if she does, will her future still be waiting for her if she does?
