Emma Watson, a brilliant research physician, has been training for the mission of a lifetime: to study living organisms in space. Jack McCallum, Emma's ex-husband, also an astronaut, never took her work seriously. Now a sudden, mysterious, and catastrophic epidemic aboard the international space station has everyone on earth panicking. Only Emma can help the astronauts isolate the deadly virus and find a cure. And only Jack can bring her back alive. Forced again to rely on one another, they must embark upon a desperate mission into the cold, dark, and airless void of space to save the station, and themselves, from a terrifying end. As they race against time, they will be forced to confront the ghost of their failed marriage, and the undeniable truth that sometimes, the greatest danger lies where it is least expected.
