Venturing into space and travelling to Mars sounds like an exotic adventure, but the reality is living in lava caves hundreds of feet below the surface of a rocky, frozen, lifeless planet is exacting on the Mars Endeavour crew. The only viable option for long term habitation lies beneath the surface of the planet, where humans can be shielded from harsh cosmic radiation.

Connor, Harrison, and Liz are senior members of the US module. When war breaks out on Earth, and rumors begin spreading on Mars, they find their core principles rocked by the devastation and loss of friends and family. Who can you trust on an international mission when your countries are at war? As the colonists struggle to figure out what really happened on Earth, grief and anger become pitted against camaraderie and the spirit of exploration.

PETER CAWDRON is an Australian science fiction writer and author of numerous novels. He lives in Queensland, Australia.
