The Far Shore of Time
Frederik Pohl
 Dannerman recovers from his ordeal he learns more about the Horch, the Beloved Leaders, and other species involved in their war. He collects information and technology, while looking for an opportunity to return to Earth and warn humanity about the coming of the Beloved Leaders. When Dannerman is asked to assist in preparing one of the former prisoners to infiltrate the Beloved Leaders he sees an opportunity to return home. He presents the plan to the Horch, and although they do not agree to it he is able to bluff his way through. He ends up back on Earth aboard one of the stealth submarines that the Beloved Leaders have placed on Earth. Dannerman is able to make contact with his government, and discovers that they are already aware of the Beloved Leaders and are taking precautions against them. However, they are not aware of the stealthed submarines. Dannerman and his alien friends are again interrogated by the American government and representatives of the United Nations, although more gently than his previous interrogators. Dannerman must serve as a translator between the humans and the aliens, because he is in possession of a translation implant from the Beloved Leaders. With information from Dannerman and help from Horch technology, the Beloved Leader's submarines are cut off from their masters and captured before they are able to unleash pockets of undersea methane gas. This strategy is the Beloved Leaders standard practice for dealing with planets that will not submit to them. Having survived the initial contact, the President of the United States prepares to release all information about the aliens and the confrontation to the world, so that humanity can prepare to defend themselves in the future.
