From the author of Gorky Park comes a novel of earth-shattering proportions. Four men cross a barbed-wire fence at Stallion Gate to select the test site for the first atomic weapon. They are Oppenheimer, the physicist; Groves, the general; Fuchs, the spy; and Sergeant Joe Pena. Four men in a covert world of soldiers and scientists, roughnecks and rougher women, all about to partake in the most important ten seconds the world has ever seen.
