A man’s hometown is drastically changed—and no one knows what he’s talking about—in this science fiction novel from the author of The Zap Gun. Following an inexplicable urge, Ted Barton returns to his idyllic Virginia hometown for a vacation, but when he gets there, he is shocked to discover that the town has utterly changed. The stores and houses are all different and he doesn’t recognize anybody. The mystery deepens when he checks the town’s historical records…and reads that he died nearly twenty years earlier. As he attempts to uncover the secrets of the town, Barton is drawn deeper into the puzzle, and into a supernatural battle that could decide the fate of the universe.
