When evil forces are going unchecked on Earth, a principled astronaut makes a spilt-second decision to try to seek justice in the only place she knows how--the International Space Station. Walli Beckwith is a model astronaut. She graduated at the top of her class from the Naval Academy, had a successful career flying fighter jets, and has spent more than three hundred days in space. So when she refuses to leave her post aboard the International Space Station following an accident that forces her fellow astronauts to evacuate, her American and Russian colleagues are mystified. For Walli, the matter at hand feels all too clear and terrifying for her to be worried about ruining her career. She is stuck in a race against time to save a part of the world that seems to have been forgotten, and also the life of the person she loves the most. She will go to any length necessary, using the only tool she has, to accomplish what she knows is right.
