In this city, everyone has a shadow.
It is not just the outline left by the light, it may also hide the secrets that a person least wants to face: desire, sin, trauma, guilt, and the darkness of human nature that has been suppressed for many years.
Lin Yan is an invisible "killer", but he never takes away people's lives. What he really killed was the shadow attached to the person. Can a person who has done many evil things become a "good person" again after losing his shadow? Who should bear the responsibility for the eliminated sins? When the shadow begins to remember, resist, and even have its own will, can so-called justice become another kind of harm?
Starting from a series of strange cases, Lin Yan gradually discovered that he had never faced only the darkness of others, but also the truth that had been buried for many years and the inescapable past. As gray shadows, lost shadows, and shadows without belonging appear one after another, the boundary between people and shadows is completely broken.
This is an urban fantasy suspense novel about sin and redemption, choice and price. What it asks is not whether people can escape the darkness, but whether you have the courage to admit your own shadow when no one decides the outcome for you.
