Jupiter & Mars is an underwater adventure set in a future-Earth in which everything science warned us about has come to pass: sea levels have risen from melting ice caps and climate change. As a result, the coastal cities are all but completely submerged. Since man's disappearance, the oceans have begun to reclaim themselves, with coral and nearly extinct creatures returning to their once-thriving levels. But the artifacts of man's presence still remain, and an elite race of whales known as the Elders enlist Jupiter and Mars to help neutralize a global network of machines that are disrupting sea life. Along the way, Jupiter and Mars will perform incredible feats and maybe even survive to tell the tale.
