Waverly is a 15-year-old girl who was born in outer space. She is currently on the space station Empyrean hurtling away from earth and toward a new future on a distant planet called “New Earth.” It will be her job to marry and have lots of babies in order to keep the human race alive. Her boyfriend, Kieran, seems made for her. He loves her and will be the future captain of their ship. But she can’t help noticing the darkly intriguing Seth who is also on board. Everything changes in an instant when the Empyrean is hijacked by its sister ship, the New Horizon. All of the adults are killed or have disappeared and the girls of the Empyrean are kidnapped and taken to the New Horizon where they will be used as breeders. On the New Horizon Waverly struggles to lead a rebellion of the kidnapped girls and back on the Empyrean, Kieran and Seth battle to take control of the remaining boys left on the spaceship. Both are caught in a life-and-death struggle in the unforgiving and dangerous realm of outer space. While I found some of the action unbelievable at times and the secondary characters poorly fleshed-out, it's a fast-paced read and an intriguing concept that would be appropriate for 7th-12th graders.
