Pressed into service when World War II breaks out in the Pacific, the U.S.S. Walker—a Great-War vintage "four-stacker" destroyer—finds itself in full retreat from pursuit by Japanese battleships. Its captain, Lieutenant Commander Matthew Patrick Reddy, knows that he and his crew are in dire straits. In desperation, he heads Walker into a squall, hoping it will give them cover—and emerges somewhere else.Familiar landmarks appear, but the water teems with monstrous, vicious fish. And there appear to be dinosaurs grazing on the plains of Bali. Gradually Matt and his crew must accept the fact that they are in an alternate world—and they are not alone. Humans have not evolved, but two other species have. And they are at war.
