In the fifteenth year of Duke Xian of Qin’s reign, the Wei army bears down on the border, and Qin is in danger. A soul awakened from two thousand years in the future opens its eyes in a small frontier town. He knows Qin will rise: Shang Yang’s reforms, the Battle of Changping, the conquest of the six states. But he also knows how it will end for everyone. This is a story of more than a century spent together and apart, from Liyang to Xianyang, from the depths of despair to the summit, as one person witnesses the entire course of an era.
