A thousand feet underground.
A billion years from Earth.
A week to live.
Keldin gave up everything to survive: his career, his community, his family. He was beaten, mutilated, and poisoned. He traveled to an alien world, passed through fire and ice and darkness and a mile of solid rock.
Armed with only the barest of tools and the briefest of training, he walks abandoned tunnels, groping in the dust for abandoned memories. He painstakingly unwinds the tapestry of nine billion lives, looking for a single thread: Ennun, humanity’s savior.
As a child, Ennun was a homeless refugee and an expatriate. He grew to become an explorer, a soldier, and the heir to a kingdom. Then he abandoned paradise, abandoned everything, to save humanity.
Then he disappeared.
For hundreds of years, the greatest historians have scoured the world for the key to understand him.
