J. Robert Oppenheimer was a brilliant scientist, a champion of liberal causes, and a complex and often contradictory character. He loyally protected his Communist friends, only to later betray them under questioning. He repeatedly lied about love affairs. And he defended the use of the atomic bomb that he helped create, before ultimately lobbying against nuclear proliferation.Through narratives that cross time and space, a set of seven fictional characters bears witness to the life of Oppenheimer. As these men and women fall into the orbit of a brilliant but mercurial mind at work, all consider his complicated legacy while also uncovering deep and often unsettling truths about their own lives.In this stunning, elliptical novel, Louisa Hall has crafted a breathtaking and explosive story about public and private tragedy, about power and guilt, and about the secrets we keep from the world and from ourselves.
