4.5 stars, rounded up because of the very last chapter. Wow.

I loved the way this story unfolded. The story is so twisted, but not in a way that feels convoluted, at least to me. I didn't feel like there were any huge AHA! moments that flabbergasted me, but each reveal just made me more and more uneasy as I read. The story unfolded at exactly the right pacing. And even though we pretty much know the story by the last 20-30 pages, the book didn't lose the tension that had built up because I still wasn't sure how all the chips were going to fall.
Most times when I read thrillers I find myself trying to figure out what the 'big twist' will be. With this book, I was so consumed with the characters themselves that I just kind of let the story happen, which made for a wonderful reading experience.
