1944, New Mexico: Alice Katz is a young Jewish physicist, one of the only female doctoral students at her university, studying with the famous Dr Oppenheimer. Her well-to-do family wants her to marry and settle down. Instead, Alice answers her country's call to go deep into the desert and lend her skills to a secret project at the heart of the fight against Germany.

At Los Alamos, Alice meets Caleb, who has been assigned to the explosives division. Around them are other young scientists and engineers who have left their ordinary lives behind, telling no one where they are going and what they will be doing.

Details of the project are shrouded in secrecy, but everyone knows it is a race against time to beat the Nazis before they create an unspeakable weapon of their own.

In this atmosphere of fear and uncertainty, and despite their many differences, Alice and Caleb find themselves drawn to one another. But as they become more and more desperate to complete their mission before the war is lost, they will face a heartbreaking choice between love for their country and love for each other...

This epic tale of love in the face of war is a poignant reminder of the consequences of our decisions, and the roles we play in history. Perfect for fans of Oppenheimer, Hidden Figures and The Diamond Eye.
