The news of her fiance's death at Dunkirk was a cruel blow for Holly Morgan to suffer. But for Holly - forced to nurse enemy soldiers back to health while her beloved Jersey ails beneath an epidemic of crime, rationing and the worst excesses of Nazi occupation - the brutality of her war has only just begun.

From the grim conditions of the hospital operating theatre where Holly is compelled to work long hours alongside the very people responsible for her grief, unexpected bonds of resilience and tenderness are forged. When friendship turns to love between Holly and a young German doctor, Peter Schmidt, their forbidden passion finds sanctuary at Half Hidden, a deserted house deep within the island countryside. A refuge where traditional battle lines recede from view in the face of more powerful emotions, it nevertheless becomes the focus for the war Holly and Peter must fight together - a war where every friend may be an enemy . . .
