After the destruction of the Ark lab, the sole surviving subject—a girl with unimaginable psychic power—wanders into the lawless, frozen wasteland of the Mongol Heleer borderlands. There, she discovers she is not the only "witch" the program created, and a far more ancient, terrifying force is hunting her.

“You broke the first rule,” Temuulen says, her voice calm as a frozen lake. “We are not supposed to remember.”

The white van skids onto the frozen mud road, its side punctured by bullet holes. Inside, the girl (Cover Name: ) clutches a worn teddy bear, her face expressionless. Blood—not hers—dries in a crack down her cheek.

But Ja-young looks past Temuulen—to the second convoy. This one flies no flag. And in the lead vehicle sits a man with no shadow.

Then, every light in Heleer explodes.

Cut to black.

“They called me a witch. But a witch is just a girl who survived the fire. In Mongol Heleer… the fire is just getting started.”
