Switching lives was supposed to be the answer, not the problem.
All Don wants is to defend Earth on his own terms. His father is hell-bent on making him into an officer, just like him. Suffocating under the weight of the family legacy, Don isn’t going to waste his last chance at freedom. He swaps lives with a trainee headed for basic. If his plan succeeds, Don will finally be able to follow his dreams, become a Space Jumper, and defend humanity against the alien invasion. All he has to do now is deceive the whole world.
