The characters develop splendidly as the chapters progresses; thus unfolding the instincts of each of them. Apart from the central plot, the book explains how media can be exploited to turn everyone against you; to make people think what you are based on forging a public opinion and luring them to believe it without facts. Also, it talks about the family bonding. No matter what happens, your family will be there to stand by your side. This is evident by the relationship showcased between Nick and his twin sister.
The heart of story is how people pretend to be someone else in order to be accepted as perfect. Despite our shortcomings, almost all of us wear masks when we face the world outside our own. We crave for people to believe that we are nice, kind, generous, helpful, etc. But the real face unveils itself in marriage.
On the whole its an entertaining read - it plays with the mind all along. And most importantly, all the themes it describes are intertwined nicely. The episodes it presents to us are perfectly structured showcasing the discipline of the author, Gillian Flynn. I am looking forward to watching the film adaptation of this novel.
