"Like Serenity on a submarine..."
The surface of the ocean has become a contested place. International shipping is forced undersea, carried out by submarines fitted for transporting cargo. Captain Sylvia Percy and her small crew run one such boat, the Prospect. They fight a daily battle to keep their rusting sub from dropping into the depths. It's just another grimy job until they find themselves pursued by a military submarine driven by some inexplicable violent purpose. To survive, the crew of the Prospect push the machine that is their home to the very edge of its capabilities, while still trying to make their delivery on time.
Try a spoonful of realism mixed into your speculative fiction. By Sound Alone is derived from science fiction themes but never deviates from a commitment to painstakingly-researched, realistic mid-century submarine mechanics and operations. With a heritage that is equal parts 1970s trucker culture and 1960s submarine movie, By Sound Alone revels in the power of confined spaces and dangerous operations that have always been the meat of compelling submarine stories. But it also breaks new ground with a setting of a fictional world where cargo submarines are a critical part of global logistics networks. It's a gripping grimepunk tale, propelled through a cinematic environment from which you will not want to surface.
