East Berlin, 1973. Herring, a disillusioned American spy, has spent the entire Cold War infiltrating the inner circles of East German intelligence for a cause he barely believes in anymore. He's seen everything and done anything his government has asked, but his latest mission pits the brilliant, embittered operative against an enemy force so vast it could obliterate all of humanity.
When a mysterious alien probe lands outside East Berlin and into Soviet control, the Americans send their top spy in to investigate. But as Herring gets ever closer to the truth at the heart of the conspiracy, he may find that the power is too dangerous for anyone to control or contain.
