In the City of Streaming Light, memory is currency and emotions are commodities. People can buy a happy childhood or sell a painful past. Lin Jing is the top "memory scavenger" in the city. His job is to clean up the memory residue that is contaminated and distorted enough to drive the owner crazy. He was accustomed to this, until he encountered a "living creature" that shouldn't exist in a pool of rotting dreams - an "echo virus" that could devour everything.
Overnight, he went from ace scavenger to the most wanted criminal in the city. Caught between order and chaos, Akatsuki, a mysterious ghost-like girl with no past, becomes his only ally.
In order to prove his innocence, and to prevent the complete collapse of this splendid city built with lies, Lin Jing was forced to embark on an abyssal road leading to the truth. What he will face is not only the pursuit by the city's rulers and the use of the rebels, but also an ancient secret hidden behind the "star core" in the heart of the city that is related to the survival of mankind.
When memory can be tampered with, when self can be defined, what is reality? And is the price of saving the world a complete loss of oneself?
