The world outside has grown toxic, the view of it limited, talk of it forbidden. The remnants of humanity live underground in a single silo. But there are always those who hope, who dream. These are the dangerous people, the residents who infect others with their optimism. Their punishment is simple. They are given the very thing they want: They are allowed to go outside.

The old world is buried. A new one has been forged atop the shifting dunes. Here in this land of howling wind and infernal sand, four siblings find themselves scattered and lost. Their father was a sand diver, one of the elite few who could travel deep beneath the desert floor and bring up the relics and scraps that keep their people alive. But their father is gone. And the world he left behind might be next.

For centuries, men and women have manned lighthouses to ensure the safe passage of ships. It is a lonely job and a thankless one for the most part. Until something goes wrong. Until a ship is in distress. In the twenty-third century, this job has moved into outer space. A network of beacons allows ships to travel across the Milky Way at many times the speed of light. These beacons are built to be robust. They never break down. They never fail. At least, they aren’t supposed to.

Famine. Death. War. Pestilence. These are the harbingers of the biblical apocalypse, of the End of the World. In science fiction, the end is triggered by less figurative means: nuclear holocaust, biological warfare/pandemic, ecological disaster, or cosmological cataclysm. But before any catastrophe, there are people who see it coming. During, there are heroes who fight against it. And after, there are the survivors who persevere and try to rebuild. THE APOCALYPSE TRIPTYCH will tell their stories. Edited by acclaimed anthologist John Joseph Adams and bestselling author Hugh Howey, THE APOCALYPSE TRIPTYCH is a series of three anthologies of apocalyptic fiction. THE END IS NIGH focuses on life before the apocalypse. THE END IS NOW turns its attention to life during the apocalypse. And THE END HAS COME focuses on life after the apocalypse.
