The Time Door

Reuben Jackson is the only one who still cares about Mars. In the shambles of the Great Collapse, Earth has abandoned the Mars explorers to their fate. But Reuben will make a stand for the Mars team—even against the powerfully united politicians and scientists. In too deep, he discovers hidden conspiracies and unexpected allies.

As the conflict mounts on Earth, time runs down on Mars. Left to face Mars alone, Commander Donegan Moynihan and his team have no hope of surviving after their supplies are gone. Willing to accept a quicker death than starvation, the explorers strike out on a dangerous mission. They venture deep inside the ancient volcano of Arsia Mons, into perils and secrets long buried. What they discover would move mountains on Earth—but will it be enough to save themselves?
