Seventeen-year-old hunter Huijie lives a double life—ordinary student by day, vampire executioner by night—driven by one goal: find the royal vampire with black markings who slaughtered her family and somehow spared her. When a powerful intruder nearly kills an elite hunter in her own room, Huijie realizes the Blood Clan is moving in the open—and the royal house is fractured by a new ruler and rebels hiding among humans. Then she meets a mysterious, unnervingly beautiful child on the mountain—cold to the touch, impossible to read—who appears just before a noodle shop burns to the ground, leaving three bodies… and no trace of him. He demands one thing: a place to stay in her home. If Huijie refuses, more people die. If she agrees, she may be inviting the enemy straight into the heart of the Hunter Organization.
