I'm the youngest member of the pest-control team in Lingchuan City. In my three years on the job, I've dealt with old buildings hollowed out by termites and cold-storage warehouses overrun with cockroaches. But I never imagined the most intractable "pest problem" would be a string of murders hidden in a haunted house.
A corpse gnawed by insects behind sealed doors and windows, the words "At night, the wind and rain came" spelled out on a wall with insect carcasses, and an old scar on my finger from ten years ago whose pattern perfectly matched the trails of the swarm...
Every rainy night, the nest awakens. And what I've been guarding all along isn't a haunted house, but the truth about the insect infestation that can drag me back into the abyss of my childhood.
