"Graduating from Harvard at the height of World War II, brilliant mathematician Charlie Fisk is assigned to the Manhattan Project. Working with some of the age's greatest scientific minds, including J. Robert Oppenheimer, Enrico Fermi, and Leo Szilard, Charlie is assigned the task of designing and building the detonator of the atomic bomb. As he performs that work Charlie suffers a crisis of conscience, which his wife, Brenda--unaware of the true nature of Charlie's top-secret task--mistakes as self-doubt. She urges him to set aside his qualms and continue. Once the bombs strike Hiroshima and Nagasaki, the feelings of culpability devastate him and Brenda. At the war's end, Charlie receives a scholarship to pursue a PhD in physics at Stanford--an opportunity he and Brenda hope will allow them a fresh start. But the past proves inescapable. All any of his new colleagues can talk about is the bomb, and what greater atomic weapons might be on the horizon. Haunted by guilt, Charlie and Brenda leave Stanford and decide to dedicate the rest of their lives to making amends for the evil he helped to birth into the world. Based on the life of the actual mathematician Charles B. Fisk, Universe of Two combines riveting historical drama with a poignant love story. Stephen Kiernan has conjured a remarkable account of two people struggling to heal their consciences and find peace in a world forever changed"--
