WHOA. I had heard this novel compared to Gone Girl on several occasions and as I was about a third of the way into this book, I could see why. The shift in perception of the characters happens much more subtly, over time, in this book. But, it's still fraught with tension on every single page that you have to keep turning. This would be a helluva book club book - lots to dissect about right and wrong and 'what would you do in this horrible situation?' kind of discussions
