I was stoked for this book based on the reviews, which compared it to Gone Girl and called it a scary thriller. Unfortunately, I was majorly disappointed. Not only did I find it terribly predictable (the "shocking" plot twists seemed pretty easy to predict) but it suffered from a problem I have with a lot of modern books and movies: Genuinely unlikable characters. I could think of no reason why these people, who not only were unpleasant but clearly didn't much care for one another, would be spending time together, hen weekend or not. While well written (and edited, which is so important in this day and age), it simply fell flat for me.
