This is the first book I've read by Gillian Flynn. There's not too much that I can say about the book. It's definitely a book that needs to be experienced and I feel like revealing too much in the review would ruin it for people and I don't want to do that. 
 Gone Girl deals with Nick and Amy Dunne. Mainly their marriage. On the day of theiir 5th wedding anniversary Amy goes missing. So what happened to her? Was she abducted from her and Nick's Missouri home? Did Nick have something to do with it? Is Amy even still alive? 
 Flynn did a wonderful job of surprising me. I started out thinking / believing one thing and slowly Flynn would throw bits and pieces of information at me that would make me second guess where the story was going. Flynn did such a great job of this and it flowed so well with the story that it never just became a device. She threaded her plot together so tightly I was very impressed. 
 Nick and Amy are both characters who have many different layers to them. I felt myself change my opinion on both characters numerous times before the end of the book. Flynn did a wonderful job exploring "double meanings" nothing was what it seemed, but it could be. Everything could be taken one of two (or more) ways. What you were seeing might be the truth or it may be a lie. 
 At first, I would have liked the book to end differently, but, upon further thought, I think that the ending served the characters best. There were some things left unsaid in the end. Just one of those things that readers have to draw their own conclusions for. 
 This is definitely the type of book that I will think about for days after I've finished it. Just thinking about the different twists and turns. I highley recommend this book, it was difficult to put down once I started reading.
