Ship with Red Hair

As a new communications officer, Darius Lever was in over his head as soon he arrived at the navigation deck on one of the few ships holding the last survivors of earth. In a fleet where each ship is home to millions of people, every decision is life or death...until a single ship makes a choice that may doom the remainder of the human race. That ship is controlled by a twenty-two-year-old girl. Darius must choose to save humanity, her life, or his own.
