Lady Elizabeth Neville-Ashford, has struggled against both her mother's expectations and the restrictions early 20th-century British society imposes upon women of "gentle breeding". Lilly longs to make a difference, to have a life of substance and meaning. Only one person other than her beloved brother Edward ever listened to what she really wanted-Robert Fraser, Edward's best friend. But that was many years ago when he was visiting and Lilly was young, and she is certain Robbie has long forgotten her. Robbie Fraser knows he shouldn't have come to the lavish ball given by Edward's parents, the Earl and Countess of Cumberland. This world is far removed from the hospital in Whitechapel where he works as a surgeon. In his work, he is fÒeted and admired by his colleagues and friends, yet his accomplishments count for nothing to the privileged few attending the Neville-Ashford gala. As he plots his quiet escape, he is stopped by a vision of loveliness-Lilly. He finds her utterly captivating. She believes he is the man of her dreams. In a few short weeks, the world is engulfed by war. As the lights go out across Europe, Robbie becomes a trauma surgeon in a field hospital on the Western Front, while Lilly breaks free of convention, as well as from her disapproving parents, leaving home and eventually becoming an ambulance driver with the Women's Army Auxiliary Corps. When she is transferred to the same field hospital where Robbie works, she hopes to strengthen the growing bond between them. Yet how can love survive the class restrictions that separate them and the horrors and suffering of the Great War?
