I resisted reading this fascinating mystery/thriller as I have an annoying habit of avoiding anything that seems trendy or popular.  Silly me!  This is a fabulous read, one that pulls you in, tricks you into a series of erroneous beliefs then sets you back up for the big fall.  It would ruin your reading experience if I told you too much about the plot.  It is enough to say that "Boy meets Girl, Boy loses Girl"... or does he?  I can also tell you that the ending transforms the story from a mystery/ thriller into a horror story.  After reading the last few lines, you'll shiver in disbelief and be glad that you have allowed yourself to be enmeshed in author Gillian Flynn's web of deceipt.  Bravo, Ms. Flynn!
