The crimes of the past-the perils of the future.

500 years ago, the world's wealthiest abandoned a ravaged Earth and left billions to die of plagues and climate disasters. Now the space colonists plan to return.

Killian Morningcloud, a discontented Earth man from the stagnating communities known as Allocations, and Natira Celestia, a video celebrity of the off-world ruling class, are on a collision course. When they discover a secret that powerful people are desperate to hide, they face a brutal test of endurance and shattered dreams.

And their fire-and-water pairing will shape the course of the whole human race.
