Theme: sacrifice and obedience; based on the story of Noah and the ark. One minute, Wade Mullens had been in Odyssey, attempting to burn his top-secret drawings for the atomic bomb. The next he knew, he was transported to a time period centuries before. A strange prophet predicts that Wade is the final sign—an end-times omen of a culture on the verge of annihilation. But a power-mad tyrant sees opportunity in the boy because of his bomb-making capabilities.
It's do-or-die time. Can Wade stop the reign of terror that the madman's bomb will surely bring?
