I read the book in my second year of college and I think that the book is severely overrated. I was recommended this book my many female friends and I was super hyped up to read it but it turned out to be very mediocre. It was fairly clear to me that the husband was not involved in the disappearance and the diary was not entirely true since the beginning. Amy was definitely smart, well planned and strategic but that doesn't excuse the fact that she is downright a terrible, spoiled person who is willing to go to any extent to get what she wants. Nick was a terrible husband but I still believe that Amy was the actual villain in the book. My negative opinion about Amy started forming after reading what she did to the other people in her lives, like her childhood friend Susan, Desi and the truck driver. Up until then, I was rooting for Amy to win. All in all, I found the book very predictable apart from the going back to Nick and the end. I did like the cool girl monologue though.
