He had always dreamed of sending rockets to the moon, but engineer Rudi Graf instead finds himself working alongside Wernher von Braun, launching V2 rockets at London for the Nazis from a bleak seaside town in occupied Holland. When rumors of a defector circulate through the German ranks, Graf—an engineer, not a soldier—becomes a prime suspect. Meanwhile, English intelligence officer Kay Caton-Walsh sets out with her colleagues to locate and destroy the V2 launch sites. But at this stage in the war it's hard to know who she can trust, and in this gripping novel by the author of Fatherland, Kay and Graf are on a collision course.
