When Nick joins a TV production to explore an old mine that took his grandfather's life, he is intent on finding out what happened in the past, maybe even finding some remains he can bury to get closure. But what he and his team find in the caves is something more sinister and deadly than they ever could have imagined. A scary story that slowly leads to a gruesome but therefore also unavoidably predictable discovery. There was some nice creepy atmosphere, but I wished the group would have been forced to remain underground the whole time. That would have added a much greater level of claustrophobia and dread. Bottom line: a solid horror novella with a consequent twist.
