In a story spun off from Hugh Howey's World of WOOL, life in the silo turns into a nightmare. Ben Logan never wanted to be a deputy—and he certainly didn’t want to be chief deputy. He reluctantly accepted the job believing his days would be full of paperwork, breaking up fist fights and searching for lost dogs. Then his second-in-command came to him and said, “We’ve got a body in the mines.” A body that’s been shredded by something with claws, and has had its heart torn out. With the aid of the victim’s best friend, Ben has to step into a role he never envisioned, tracking the killer as it leaves a trail of blood throughout the silo.
