A second chance for humanity? Or time to pass the torch.

The Zenith Train is primed to break a world speed record. But when the promotional stunt goes horribly wrong, billionaire philanthropist Griffin St. Clair and a group of VIPs find themselves in a world where the human race may be extinct. An apocalypse has spared them. What now?

They are not alone. In an uncanny forest devoid of other life, they encounter seemingly benevolent spectres and psychic predators who may be the next step in evolution.

Simply surviving will take everything they’ve got. Do they have a duty to do more?

Are the Zenith passengers a second chance for humanity on Earth? Or is the human era truly over?
