this book was gripping enough that I finished it in two days. 
Although I was expecting more out of this book, it was still enjoyable, albeit lackluster.
The premise is very exciting, but the actual events are not as much. Honestly, I did not expect the plot twist, but the buildup of events just wasn't that exciting or mysterious. I never felt that fear and dread, that I usually feel with psychological thrillers. 
You can clearly tell that this is the debut novel of the author, and I'm looking forward to read more of his works in the future.
