Riley Sager excels at setting a creepy atmosphere and this book is no exception. The building of tension was really good as the reader follows Jules in her journey at The Bartholomew. The ending twist is definitely not one I saw coming (and it's a little out there), but by setting the book both as flashbacks and the current time, the reader is able to try to piece together what happened.

Pros:
- creepy atmosphere
- great gothic setting
- plot twist that was actually surprising

Cons:
- the "too good to be true" aspect makes the main character a little unbelievable
- the scale of the twist took away from it a bit
