In Part 2 of the Mars 2-part epic, temporal reconciliation has successfully brought the antediluvian Martians from 3 billion years ago into the current 25th Century's terraformed Mars human colony. This coincides with a political crisis in which Mother Earth may lose Mars to a megalomaniac who has yet to learn of the " tempconciliation ." These two plot lines collide explosively into a bizarre and implacable mix of political disturbances on a planetary scale and and existential crisis on an interplanetary scale. Time is running out on both, and both Martians and humans face the possibility of oblivion.
