Thorium Blues After helping quell the second Martian revolution, Chris Lafontaine needs an adventure. Tharsis City needs replacement fuel for the aging power reactors that allow its farm domes to provide food and oxygen. Chris agrees to lead an expedition up Mariner Valley to the North Polar Basin to explore known thorium deposits. Leading a motley crew aboard four vacuum tractors, the only trouble Chris expects is from the hostile environment of the red planet. The trek is difficult enough, but at their goal three armed Chinese tractors block their way. Their leader tells Chris that the Peoples’ Republic claims exclusive rights to all mineral deposits in the Northern Lowlands. He orders them to leave. Chris refuses, hoping to defuse the conflict. When the Chinese tractors threaten to imprison the team, Chris realizes that the prospecting tools they brought along can also beused as weapons to defend the team. He needs to find a way to evade capture, complete his mission, and bring his crew members back to Tharsis alive.
