Many of the Young Adult dystopian novels that came out after The Hunger Games were disappointing to say the least, but this book explores the theme of totalitarianism better than most. In outer space, two ships are on the way to populate a distant planet after Earth’s collapse, except onboard the New Horizon the women are all sterile. Desperate to procreate, the crew mount an attack on their sister ship, Empyrean, killing all the adults and kidnapping the female children. Held captive, fifteen-year-old Waverly wages careful resistance. Onboard the Empyrean, her captain-in-training boyfriend, Kieran, fights to get her back with nothing more than a crew of boys to man the ship. Can Kieran, who uses to religion to maintain strict control, fend off the brilliant Seth who is of a much more liberal mindset? Which boy will Waverly prefer if rescued? There’s a depth to this book not present in most YA novels. The author masterfully weaves in themes of religion, good versus evil, and reproductive rights, while still managing to provide a thrilling, technically proficient Sci-Fi adventure.
