On the wasteland, technology has withered, and knowledge has become taboo.
The AI Apollyon rules over the last remnants of humanity, creating emotionless Apostles to maintain absolute order.
Su Mian runs a small eatery in a town deep in the wasteland. She has forgotten an entire year of her past and remembers only the parting words her mentor and senior fellow disciple left her:
“Stay here and wait for us to come back.”
Then, one night, Jiang Chen, Apollyon's enforcer, steps through her door.
He is the most powerful Apostle, yet he possesses a tenderness and memories that should not exist.
“You forgot me,” Jiang Chen says, looking at her. “But I remember you.”
A secret capable of shaking the wasteland lies hidden in the gaps in her memory.
