OK, I'm about a year or two after everyone else - I normally don't like over-hyped books. But wow, this one is well worth the hype! Gillian Flynn manages to twist and turn things around, leaving the reader suspecting but at the same time completely uprepared for the next turn of events. Masterly! When Amy disappears on the morning of their 5th anniversary, Nick starts to wonder how well he really knew the woman he is married to. The police suspect him of murder, her diary shows she was afraid of him. Nick claims he is innocent, but can we believe him? Brilliantly told through both Amy's and Nick's perspective and full of gripping suspense. Heartily recommended!
