Author Richard Dinnick brings us the tale of the Doctor, Amy, and Rory as they materialize aboard a ship orbiting an ocean planet. The Doctor walks in on the ships captain and uses his physic paper and tells her that he's from the home office on Earth. The Captain unwillingly agrees to let him Amy and Rory to come along on their mission. As they board the submarine that it loaded onto a drop ship the Doctor begins to feel that something isn't right. And he sniffs out the problem after taking a small submersible out to look around. He and Amy are captured but the Shoal only speak with colors and the Doctor must build a translator so they can communicate. This is a fast passed story and well worth the read, I highly recommend it for all Doctor Who fans.
