Colony One Mars All contact is lost with the first human colony on Mars during a long and destructive sandstorm. Satellite imagery of the aftermath shows extensive damage to the facility. The fifty-four colonists who called it home are presumed dead. Three years later, a new mission sets down on the planet surface to investigate what remains of the derelict site. But, it's not long before they realize the colony is not as lifeless as everyone thought. Someone is still alive -- hiding out somewhere. Yet, before they can find the elusive colonist a strange illness starts to affect the crew. Pressure now mounts on Biologist, Dr. Jann Malbec, to locate the source and find a way to fight it. However, as she investigates she begins to suspect a dark and deadly secret lurking within the colony. A secret that threatens not just the crew but the entire population of Earth. With limited resources and time running out, she must find some answers and find them fast. Because if she doesn't, none of them will be going home. Colony Two Mars The only survivor of the ill-fated ISA mission is now stranded on Mars. Having been designated a bio-hazard by Earth, any hope of returning home is all but gone. She is alone, isolated, and abandoned. That is, until another human shows up in the main colony airlock. However, he's barely alive and soon dies without regaining consciousness. More disturbing though, a DNA test identifies him as a colonist who has already died, several years earlier - impossible as that may be. Nevertheless, there is only one place he could have come from, the mine on the far side of the Jezero crater - Colony Two. An outpost they had presumed was long dead. But if he survived, maybe there are others still alive? She now has no choice but to attempt the dangerous journey across the crater to investigate. Because if she doesn't find some answers soon, her only future is to die alone on Mars. Colony Three Mars 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. Worse, these newcomers are well armed, and prepared to go to war with each other to win control of the colony and its people. But Dr. Jann Malbec has a secret, one that she could use to spare the colony and save the colonists from this fate. 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?
