In this world, people only exist if their names are written in the register. Every day, copyist Ji Chi writes his younger sister's name on his arm, watching as everyone forgets her. To write her back into the Great Register, he gets crossed out himself and walks into the nameless Wanye. There, every morning, people call out to one another so they won't lose themselves along the road.
From the border town to the forest of steles, from Zhaojing to the Eastern Sea, he will learn who wrote this world, where the erased names went, and why there must always be one line left blank.
