A British nurse in WWI German-occupied Brussels, Evelyn Marche spends her days at the hospital and her nights working at a café . . . or so it seems. Eve's most carefully guarded secret is that she also spends her nights carrying out dangerous missions as a spy for a Belgian resistance group.

When a plane crashes as she's en route to a rendezvous, Eve is the first to reach the downed plane and is shocked to recognize the badly injured pilot as British RFC Captain Simon Forrester. She risks her life to conceal him from the Germans, but as the secrets between them grow and the danger mounts, can they still hope to make it out of Belgium alive?
