Germany, September 1944: dozens of cities lie in ruins. Enemy armies are at the gates. For the Thousand Year Reich, time is running out. Desperate to avoid the humiliation of unconditional surrender, German intelligence launch Operation Finisterre—a last-ditch plan to enable Hitler to deny the savage logic of a war on two fronts and bluff his way to the negotiating table. Success depends on two individuals: Stefan Portisch, a German naval officer washed ashore on the coast of Spain after the loss of his U-boat, and Hector Gómez, an ex-FBI detective, planted by Director J. Edgar Hoover in the middle of the most secret place on earth: the American atomic bomb complex. Both men will find themselves fighting for survival as Operation Finisterre plays itself out.
