Having recently finished the Gone Girl book (my first read book for 2015), I did really enjoy it. I haven’t seen the movie yet, but the twist in the movie is well set up. The book plays around with the unreliable narrator by making both the husband and wife that the book is set around unreliable. Just when you thought that you were getting a handle on what was happening, it then proceeds to pull the rug out from underneath the reader with a major twist.
Gone Girl had no set hero or villain. In some ways, it was just 2 bad people and one just happened to be much worse when provoked. With no reliable narration happening from either viewpoint, it is always difficult to know what is going on. I would definitely recommend this as a good read to pass a couple of days and a book that you want to talk about.
