A brave and buzzing new world. Most of the First Hundred have died. Those that remain are like walking myths to Martian youth.Earth has grown too much Chronic overpopulation, bitter nationalism, scarce resources. For too many Terrans, Mars is a mocking utopia. A dream to live for, fight for… perhaps even die for.
