Grim and inexplicably gloomy. Gruesome in some parts, too. 
 I also liked the way the author wrote it, and how the author sequenced the events, how much she kept, how much she revealed. It was all in the timing, and she executed it nicely. 
 The plot twist was unexpected as well. 
 It was like reading a creepypasta in the middle of the night. It was enough to keep you on your toes, and keep you looking over your shoulder to see if someone was there. Thankfully, there wasn't, though. 
 Or was there?
