In a desert outpost, nuclear scientists and their families face the toll of the secrets they keep from the world and from each other in this gripping wartime novel from debut author Galina Vromen.

Los Alamos, 1943. The US Army has gathered scientists to create the world's first nuclear weapon. Their families, abruptly moved to the secret desert base with no explanation, have simple orders: Stand by. Make do. Above all, don't ask questions.

Christine, forced to abandon her art restoration business in New York for her husband's career, struggles to reinvent herself and cope with his increasing aloofness.

Gertie, the inquisitive teenage daughter of a German Jewish refugee physicist enlists Christine to help her unravel hidden truths and deal with parents haunted by their past.

Gertie's father, Kurt, anguished by what the Nazis have done to his family and bent on defeating them, carries burdens he longs to share but cannot confide in his wife-leading him to find comfort elsewhere.

And Jimmy, a young army technician, falls for Gertie but is unsure if even her deep affection can overcome his agonizing self-doubts.

Will so much secrecy save them or destroy them?
