My wife and I have a reading list that we have been working our way through for a while. We add titles occasionally. I had heard about this one, but very tangentially. Gina heard very positive things, so she added it to our list. 
 I'm glad she did. 
 This review will be brief because one cannot really talk about this without revealing spoilers. The writing is masterful, depicting multiple characters and view points convincingly. Nick and Amy have left New York City, which they loved, and returned to Nick's hometown in Missouri. Nick leaves their house on the morning of their anniversary. When he returns, Amy is missing and the place is visibly a crime scene. The story unfolds with back and forth narratives representing Amy's (historical journal entries) and Nick's (present events). Flynn strings you out expertly, tantalizing you with information, innuendo, and clues, while tying into the larger media spectacle that often accompanies such events. Gone Girl will take you on an unconventional mystery, and along the way you not only get excellent shocks but are treated to fantastic writing.
