Sea City: The third helix

When the imminent death of a far-flung planet causes its inhabitants to scatter seedpods throughout the galaxy, one of these meteors plummets deep into Earth's ocean floor. In time, the sea and the stone give birth to aquatic humanoids, the first sentient beings on this once-lifeless planet-and so begins Earth's epic tale of woe.

Darkening the history of the Aquatics is the ill-fated Hyperion, the jealous and paranoid prince of the Pacific, who, in a failed attempt to murder two Aquatics, inadvertently gives rise to a new land-dwelling life-form: the mouth breather. This marks the first steps of human history.

Now, thousands of years later, Earth faces its own impending doom as global warming threatens to submerge the entire planet. But this doesn't just spell the end of life for humans. The Aquatics are also suffering from the ecological imbalance. And if either hopes to survive, they must trust each other and work toward a shared future.

But the long-banished Hyperion has been brooding, and he may prove to be the supreme danger-unless someone can wield the trident stuck in the Sea Stone.
