Honestly speaking, I've started this novel by the reputation floating on the web, and very soon, I've started to be fascinated with a peculiar story development - i.e., husband, wife, husband, wife ... It reminds of the 80's movie named "The War of The Rose". Actually, the "Gone Girl" seems to be the even more upgraded version of it. Amy as a wife, more or less, is spooky. Though the end of story is surprisingly flat - I don't want to be a spoiler, I've enjoyed this novel very much.
