Now that the truth of the genetic experiments on Mars has been revealed, new missions are on their way to gain control of this extraordinary technology. In the process, they seek to exploit and enslave the colonists-turning them into nothing more than lab rats.

However, by using it she will almost certainly doom Earth to a planet-wide pandemic of apocalyptic proportions. Yet she must choose. Earth or Mars-which is is going to be?
