Mars Endeavour

Venturing into space and traveling to Mars sounds like an exotic adventure, but the reality of living on a rocky, frozen, lifeless planet is exacting on the Mars Endeavour crew. The exhilaration of reaching the surface of Mars has worn off for the public, and the exploration has moved into its scientific phase. The only viable option for long-term habitation lies hundreds of feet beneath the surface, in lava caves that shield humans from harsh cosmic radiation. Connor, Harrison, and Liz are senior members of the U.S. module. When war breaks out on Earth and rumors spread to Mars, their core principles are rocked by the devastation and loss of friends and family. Whom can you trust on an international mission when your countries are at war? As colonists from different nations struggle to figure out what really happened on Earth, grief and anger become pitted against camaraderie and the spirit of exploration.

After almost dying on Mars, astronaut Liz Anderson returns to Earth, but not to a hero's welcome. America is in turmoil. The war is over, but the insurgency has just begun. So while life on Mars may have been deadly, at least up there she knew who the enemy was. Along with her, Liz has brought the remnants of the artificial intelligence that waged war on two planets. Buried somewhere deep within the cold electronic circuits lies the last vestiges of her dead partner Jianyu. Liz is torn, unsure whether he's somehow still alive in electronic form or just a ploy by an adversary that will go to any length to win. Heartbroken and treated with suspicion, she finds herself caught up in the guerrilla war being waged on Earth, wondering if the AI threat is truly gone, or if it has only just begun.
