Couplers 2: Empty Mansions

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.
