Gone Girl: Reaction/Thoughts

Gone Girl talks about two characters named Nick and Amy.  These characters seem complete opposites  in ways, but also compliment each other.  The fellow, Nick, is more in sync with his twin sister Go than with Amy.  Nick and Amy have a different relationship than he has with Go.  They met at a party and according to Amy they fell in love on the first day.  Continuing in the story to a year later it seems that they no longer have that spark when they are married.  Today is their wedding anniversary, their 5th to be exact, and something unexpected happens.  Amy disappears.  The story revolves around Amy disappearing and gives some real suspense.  A relationship that seems to be dying is alive and well when we see how much Nick is concerned about her missing.  A man that could barely remember important moments of their relationship must find his wife that is missing.  The people of the town become suspicious as he showed a strange relationship with his wife and Amy was a girl that could put anyone on the edge of anger.  The town suspected that Nick killed her.  I became suspicious of a different person, his sister.  Their relationship was too perfect and she didn't really like Nick and Amy's relationship.  Go said things jokingly about how she didn't really like her but Nick never really made anything of it.  The book is really great by the way it introduces the characters.  The couple seems to be somewhat annoyed with each other, but murder was never hinted as one of their motives.  Neither of the people showed any hate to each other so it leaves the reader wondering who the killer is.  But the book couldn't have introduced these characters in such detail for no reason, the people introduced were suspects except for, of course, the victim Amy.  Go and Nick had a relationship that was being interfered with by Amy.
