You'll never discover the secret if you stay safe at home.Like generations before them, cadets Adam and Dawn have always lived aboard the asteroid. But past generations have never experienced a threat like this: Robotic Alien Technology (R.A.T.) is attacking the spaceship--with the intent to destroy everyone on board. Dawn and Adam are two of the best new Coupler pilots, but they're also famous for their clashes. When a family crisis and a R.A.T. sighting coincide, Dawn has to call on all her inner resources to stay focused on the mission. A deep space discovery lies ahead, threatening to forever alter the ship's future--and every life on it.
