Alice Katz is a young Jewish physicist, one of the only female doctoral students at her university, studying with the famed Dr. Oppenheimer. Her well-to-do family wants her to marry a man of her class and settle down. Instead, Alice answers her country’s call to come to an unnamed city in the desert to work on a government project shrouded in secrecy. At Los Alamos, Alice meets Caleb Blum, a poor Orthodox Jew who has been assigned to the explosives division. Around them are other young scientists and engineers who have quietly left their university posts to come live in the desert. No one seems to know exactly what they are working on-what they do know is that it is a race and that they must beat the Nazis in developing an unspeakable weapon. In this atmosphere of fear and uncertainty, and despite their many differences, Alice and Caleb find themselves drawn to one another.
