Her parents were killed when the Germans invaded France, leaving her all alone to care for a sickly aristocrat. As she grew into young womanhood, she found purpose in helping the French Resistance. She lives under constant threat of disappearing in the dark of night, never to be seen again, like so many others during the Nazi occupation. Now, on the night of June 5, 1944, she is totally unprepared for what comes floating down from the sky into her life. He was a young cowboy from Montana who volunteered to fight for his country as soon as he was old enough. The Airborne trained him to deploy by parachute, and fight behind enemy lines.

Neither expect the improbable love that blossoms under the cover of stardust.
