Mars invites scientists to participate in terraforming experiments which brings the Mavrek team all the way from Terra. But minutes after landing on the space station, Dr. Mark Warren is accused of murder. The warm welcome continues with an attack on his spaceship, then three Terrans are found dead, and killer cyborgs are spotted. Authorities immediately conduct a massive hunt throughout Martian space and terrible new enemies surface with a direct link to Warren's old nemesis. On the planet, the same fugitives hunting Warren also threaten the downfall of Mars itself. The high-octane x-military Mavrek crew battles arms dealers, mercenaries, an infamous hacker, clone trafficking, and an insidious female enemy who will kill to avoid capture. Perhaps they'll save Mars...if they don't die first.
