Gone Girl by Gillian Flynn

While I enjoyed this book from the start, as layers started to peel back and lies started to be exposed, I was drawn even more to the story. I loved the way this story revealed the lies the characters told each other, and the plotting and counter plotting of the protagonists, Nick and Amy Dunne. When Amy disappears on their fifth wedding anniversary, we see the facade they built start to crack, and gradually learn how this couple brings out both the best and the worst in each other. I'd highly recommend this book as a summer read.
