Caleb and Sally are young, in love, and alone together in paradise—like Adam and Eve, except their Eden is a giant greenhouse adrift in space. And though they have no memory of how they got there, they keep being assailed by visions of a scorched Earth.

When other people start waking up, Caleb and Sally keep to themselves. But they know it’s only a matter of time before they’ll need to confront the mystery of what’s happened to them. What they don’t anticipate is the act of brutal violence that sends them running for their lives.

As conflict rages among Earth’s other refugees, the lives of everyone may depend on Caleb and Sally finding a way to communicate with the elusive alien creators of their artificial world.
