It is 73 A.D.--after Death, that is. Ninety percent of humanity has been wiped out by plague; rival factions are warring for control of a crumbling civilization. The enclaves struggle against the forces of destruction to preserve the building blocks of our culture. They select an unlikely hero. Mordecai, an itinerant peddler and part-time magician, embarks on an incredible wagon journey across the heartland of America. Meanwhile, in an attempt to head off another outbreak of plague, the Martians send vaccine to a desperate earth.
