In a world flooded and irradiated by a nearly forgotten cataclysm from generations passed, all that remains of civilization clings to life in two war-torn, city-sized submarines. For fifty years, the only peace between them had come from separation. Now, young council woman Ralla Gattley has uncovered mysteries that will bring these two factions face-to-face, initiating a series of events that will forever change their undersea world. She didn't expect to meet Thom Vargas, a bored fisherman and aspiring drunk who merely wants to climb one rung on the social ladder. Little did he know that single step may well put the fate of the world in his hands.
