Tina Mains knows she doesn't have to worry about being ordinary. She's known since she was quite young that she's the clone of an alien war hero, hidden, disguised, on Earth, and when the time comes, the beacon implanted in her body will activate, and her life will change. In the meantime, she just has to survive high school.
When it happens, though, suddenly she's being hunted by the enemies of the woman she was cloned from before the starship that will take her to her destiny even arrives. When it does, barely in the nick of time, she and her best friend, Rachel, are injured, and need the resources of the ship's sick bay before anything else.
But the ship is more battered, worn, and short of crew than it is a shiny, powerful battle cruiser, and it turns out that the Royal Fleet has been counting on the return of their late hero more than she had imagined possible. Tina, Rachel, and four more teenagers they recruit using video games, soon find they will need to learn fast, and start coming up with their own ideas, if they're going to face anything other than the defeat and destruction of the ship they're on.
