The true tale of the monster Billy Dean, telt by hisself

All his life Billy Dean has known only the world of his bedroom and the sights, sounds, and scents of his father and mother. One day his father disappears, and his mother is allowed to finally show Billy the wider world outside--a broken world, which he has been brought up to save. He is the Angel Child, they tell him, and he must fix every mysterious thing that went wrong on the day of his birth.
