I think this novel also poses the question of how well you know another person, even one whom you may spend most of your waking hours involved with. In some cases, I think the false fronts put up by Amy and Nick are incredibly realistic and plausible, but I don't think that it is a common situation that couples find themselves to be in. While part of the joy of being in love is always finding new things to love about the person you are with, I think that it would be relatively hard to be with someone for a prolonged period of time and be able to hid behind a false persona. In the case of Amy and Nick, I think that this showed an extreme example of a false front being put up for someone else's benefit and that a person willing to go to those extremes may not be fully chemically balanced. While the book stops short of too deeply exploring the idea of potential mental illness, I think that it is certainly an under current throughout the novel.
What did you think of Gone Girl? Were you in awe of Flynn's well-crafted storyline? Or were you left wishing that she had left her audience with a more sucinct ending? Did you enjoy the dueling narrative, or would you have preferred a more streamlined, single-person view? I know that this book has been a big hit this summer, and I would love for you to tell me what you've thought!
