No other word to say than phenomenal. I was instantly drawn in from the beginning and was unable to put the book down until I finished. A shout out to Goodreads for the opportunity to read the ARC when it first came out . This is definitely one of my top favorites of all time. I have not read a book that has captured me like this in a long time. Kudos to the author for a first . It will suck you in and you can't let go . Its just that good. Psychological thrillers are always my favorite but this one is the best one I've seen in a long time. I can't wait to see what he writes next. I'll be waiting in line for his next book , whatever it is. If you haven't read this book, go out and get it.
