The sequel deals with the fallout of human reaction to the discovery of another life form, and the schism which develops between the two planets. There had been such an emotional and promising beginning.A second discovery on Mars throws the tenuous relationship into potential meltdown.

Further investigation of the second discovery sends a very sobering message to Earth.
