GROUNDFALL

It was the planet that would save humanity. Then the colonists started walking off into the dark — and coming back wrong.

Dr. Maren Cole crossed forty years of empty space to read a whole new living world. Then a girl vanishes from inside the wall. Then another. No bodies. No trail. Just the shape of where a person used to be. Kade Bishop wants to wall the danger out. Maren wants to understand it before it's too late.

DEADFALL

It doesn't hunt you. It saves you.

A belt of ash and burned ground is all that stands between Longlight and the thing that takes people. Every night, through the window before dawn, the colony's own taken walk the line and call inward. They are obscenely happy. Because Elpis was never laying siege to the colony. It's mounting a rescue.

NIGHTFALL

For an age, nobody ever asked it a single question.

The siege is over, and that is worse. Two hundred pale faces stand with their backs to Longlight, aimed at the dark, listening to somewhere else. Nadia Vos counts the drums and runs the arithmetic of a colony with a war behind it and no war left to fight.
