From the critically acclaimed author of The Baker’s Secret and The Curiosity comes a novel of conscience, love, and redemption—a fascinating fictionalized account of the life of Charlie Fisk, a gifted mathematician who was drafted into Manhattan Project and ordered against his morals to build the detonator for the atomic bomb. With his musician wife, he spends his postwar life seeking redemption—and they find it together. 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.
