We named it the rapture virus.

Then it killed us.

Ben Gardiner used to be an expert on virtual reality. But the world he knew is gone – and now he's not even sure about real reality. Heaven and Hell – whatever they are – seem to be strangely closer to the physical world. He's glimpsed what may as well be Heaven. He doesn't comprehend it, but it's worth living for.

When he's chained to a tree and left to die by a guy playing demon hunter, Ben realizes that the door to Hell might also exist – and someone is trying to pry it wide open.

One thing's for sure: in a world scourged by the rapture virus, it's going to take every ounce of his will to live, his puzzle-solving brain, and his courage to survive the endgame.
