The increasing warmth between Russia and various NATO countries has led to a corresponding chill between Europe and her American allies. Now the American are leaving Europe — and international tensions are rising. Martin Hepton is a technical working on the Zephyr programme, monitoring the program of Britain’s only spy satellite — a satellite now invaluable to the UK as, with the enforced departure of the Americans, all technological support from the US has been cut off. Mike Dreyfuss is a British astronaut, part of a Shuttle crew charged with launching a new communications satellite for the US government; a man distrusted by his fellow astronauts because of the current political situation. When Zephyr suddenly and mysteriously goes briefly off the air and a colleague of Hepton’s confides his suspicions to him, Hepton finds his own survival at risk — apparently from some very official sources indeed. And Dreyfuss, sole survivor of a fatal shuttle crash, a man on the run in a hostile America, has the only key to the riddle both men must solve if they are to stay alive
