Star City (1970)

A propulsive, paranoid thriller that takes us back to the key moment in the alt-history retelling of the space race — when the Soviet Union became the first nation to put a man on the moon. But this time, the story is explored from behind the Iron Curtain, showing the lives of the cosmonauts, the engineers and the intelligence officers embedded among them in the Soviet space program, and the risks they all took to propel humanity forward.
