Sarah "Space" Allen begins as a goody-two-shoes student with many academic achievements and a 4.0 GPA. But many of those skills are rendered useless when the world comes to an end, and she is forced to adapt to her surroundings and pick up a gun, fighting alongside her friends to survive. Early on in the story she bonds with Anikan, the two of them eventually confessing their feelings for each other after Anikan rescues her from a group of bandits who kidnap her. However, their relationship is criticized by Quinn, who the foundation for their relationship is because of their attempts to cope with the life and death situation they are in. Nevertheless, they stay together until the end of the book, where Space is separated and goes missing during the bombing. She is kidnapped by a Russian Strike Team in the chaos, and imprisoned for nearly two months before being rescued by Anikan. During her time there, she falls in love with a fellow inmate, a girl who is later executed before her escape, and comes out to Anikan and ends their relationship after being saved. Despite that, the two remain good friends.
