The Empyrean and New Horizon ships are on a course for the New Earth. The New Horizon was supposed to be ahead of the Empyrean until one day they see the New Horizon right next to them. The New Horizon is infertile and decide to kidnap all the female children on board the Empyrean. A very disturbing and adrenaline filled fight while Waverly is aboard the New Horizon trying to find a way home back to Kieran and to save the few adults left that have been captured. Kieran is left with the other boys on the Empyrean and they must fight to keep the ship working. I found the story very captivating, scary, disturbing, and surprising. I would say a mix between Across the Universe and Divergent. Not as good as those but still a good story.
