If your looking for a good psychological thriller this is it right here. The premise itself is interesting but Hendricks and Pekkanen take it one step further and end up totally creeping you out. Switching from the third person to the second person in the first couple chapters adds to the terrifying atmosphere the book carriers. Jessica is an interesting character and we learn more about her through the answers she provides rather than natural circumstances throughout the book. I think this is a genius way to write a book. It keeps the reader engaged and looking forward to when Jessica sits down to answer some more questions. The vibe of the book really carries through and is a must-read thriller for anyone interested in the genre.
