The Devil's Mountain is a short yet slow-burning horror story that drips with atmosphere. I enjoyed imagining Harding's rich descriptions of the eerie, brutalist architecture and how it had been vandalized and neglected in the years since its abandonment. He writes Dylan and Nikki with high-spirited harmony, which increases the horror, since the reader already knows something horrible is about to happen to them. My only criticism is that I would have liked more description as to what that horrible thing actually was, since my imagination had been drifting to many possibilities. In all, I thought this was a unique and engaging story, with an environment that I would love to see depicted visually, since it was so interesting to try and picture it myself.
