The sole 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 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.

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?

Xenon Hybrid, the Red Planet's ceremonial head-of-state, has not been seen for many years after withdrawing to an isolated enclave in the far north where he steadily built up a following of citizens seeking out an alternative lifestyle. They bother no one, and no one bothers them. But when an Earth-bound ship explodes on the launchpad in Jezero City, and the DNA from two bodies recovered at the site are found to be an exact match, Dr. Jann Malbec is convinced that they are the product of a covert cloning program. More troubling still is that the DNA is a very close match to the reclusive and enigmatic Xenon. Meanwhile, newly promoted Mars Envoy, Mia Sorelli, finds herself stuck on the planet after her ride back to Earth is now a charred hunk of metal. She begins to get an uneasy feeling that someone may be trying to assassinate her, and Mia's suspicions start to focus on a clandestine group of Xenon's followers. As these parallel investigations begin to converge, it becomes apparent to both Jann and Mia that the peaceful and simple lifestyle of the Xenonists is not all that it seems. There is a darker ideology bubbling underneath the surface, one that threatens to bring catastrophe to the entire population on Mars. But will anyone believe them in time?

When a colonist dies in tragic circumstances, just a few sols before a major terraforming experiment, Dr. Jann Malbec begins to suspect that all is not what it seems. Her fears begin to grow when every attempt she makes to investigate the death is thwarted by the ruling council on Mars. In desperation she resorts to secretly recruiting a recently arrived colonist, Mia Sorelli, an ex-cop with a troubled past, to quietly look into the incident. But Mia has some very good reasons why she left her old life on Earth behind. Nevertheless, she reluctantly accepts the assignment even if it means hooking up with the malcontented, semi-sentient droid, Gizmo. But what Mia uncovers goes way beyond anything she or Dr. Malbec could ever have imagined. As she investigates she begins to suspect that a terraforming experiment may be compromised by those who seek to undermine the future of the colony. Mia must now face down her old fears if she is to save, not just herself, but the entire population of Jezero City.

A one-way journey to Mars may be a mistake. Welcome to the first book of the On Mars series, a story of our near-future. Before you volunteer to settle on Mars, read Emma's struggle to slip the bonds of Earth and survive on a hostile planet. There are eight settlers on Mars until the colony's psychologist walks out an airlock to die on the cold, airless sands. Emma and her crewmates, the next mission of settlers, launch from Spaceport America despite the tragedy and despite their own misgivings. They take a tabby kitten with them, as requested by the survivors on Mars, and hope to revive the shocked colony. Emma leaves everything she knows behind, including a sometimes-boyfriend who's dropped from the next mission - all for a chance to explore the Martian surface in her robotic walkabout suit. Her arrival on Mars isn't welcomed by all the colonists, and the mission loses more lives and vital supplies in a crash landing that may not be an accident. Crippled by an inexplicable sense of desolation, they face an unforgiving planet and even Earth may hold danger. The question isn't if the colonists will explore, but if they'll survive at all.
