Zack Vernon is an immortal Observer sent to watch the world on behalf of the Creator. When his suicide attempt fails spectacularly and earns him a spot on the national news, the other Observers are drawn to him.

They believe Zack to be the reincarnation of a rebellious Observer from a previous world. Several of them plan to punish him for the sins they believe he committed. One of them wants back the man she has loved through hundreds of worlds. But Zack remembers nothing before the present. All he wants is a chance to end his life.
