The darkest of apocalypses was the final push for humanity to discover time travel. Humanity went back in time on secret missions to gather plants, soil, food, the basic of human necessity to try and rebuild a broken earth. Two hundred years after time travel is discovered, the earth is finally beginning to heal.

But six months ago, Silas Clark returned from a mission as white as a ghost and refusing to talk about what he'd seen. Soon after, the time machine started acting strange. Everyone knows Silas is the key to fixing it, but between a choice of saving humanity and facing what he saw six months ago, he doubts the fragile civilization is ready to hear the truth.
