used to dream of sending a rocket to the moon. Instead he has helped to create the world's
most sophisticated weapon: the V2 ballistic missile capable of delivering a one-ton warhead at
three times the speed of sound. In a desperate gamble to avoid defeat in the winter of 1944
Hitler orders ten thousand to be built. Graf is tasked with firing these lethal 'vengeance
weapons' at London. Kay Caton-Walsh is an officer in the Women's Auxiliary Air Force who joins
a unit of WAAFs on a mission to newly liberated Belgium. Armed with little more than a slide

sites. As the death toll soars Graf and Kay fight their grim invisible war - until one final
explosion of violence causes their destinies to collide ... 'A riveting read with a corker of a
twist' Daily Telegraph 'Supremely readable' Observer 'Delivers one hell of a punch' Express
