This is a book that takes place over the course of three days which means that the story moved quiet quickly. I think that this was a great read to start October off with because the sanatorium turned hotel was definitely a creepy setting for this book.

I found that most of the characters were decently fleshed out. I think that the only issue that I had with our main character was so meek for the first quarter to half of the book that when she started really investigating things it almost felt like two different characters to me. 

I also thought that the main motivation for the "Big Bad" was understandable but also didn't completely make sense to me as to why they did what they did for the whole story. 

I think that for me this was such a gripping story that I could not put it down and even though I had issues I still think that the twist and turns of the mystery were so fun to experience.
