After the Cataclysm, the world no longer belonged to the human race.

The Shadows are formless, sentient entities capable of taking on the shape of a human, but only in darkness. In the presence of falling light, they dissolve like smoke, yet at night they become predators, feeding on human warmth and consciousness.

During the first months, they simply killed. Then... they began to learn. First—how to imitate movements. Then—speech. And then—human memory. Some of them learned to cut off human faces, turning them into masks—and to live among people. These are the few, the rarest and most dangerous of all Shadows.

Humans learned that Shadows could mimic them far too late.

Too late—because it wasn’t mimicry. It was stolen skin.

On their own, Shadows are nearly shapeless beings made of smoke and ravenous hunger. But to survive, they need a host.

Soon, the survivors began finding bodies—without teeth, eyes, and the skin of the face—and realized that the enemy walked among them even during the day.

Dexter is a Shadow, one of those rare creatures who managed to adapt to sunlight and hide in a human form. A skillful predator who has tasted human consciousness, desires, and curiosity.

He lives among the remaining humans, studying their habits, emotions, and voices, and has learned to shift between forms: human by day, and his true monstrous self by night.

The heroine is one of the few survivors. One evening, returning to her shelter before sunset, she discovers an injured man—pale, emaciated, with torn flesh on his side as if ripped by claws.

And the girl makes a mistake she has never made before: she helps him, unaware that she is dragging pure evil into her shelter—evil that has merely decided to play with her human emotions and kindness.
