This book surprised me, both in how much I enjoyed it and the ending. It's been a long time since I was truly surprised by an ending in a thriller, and this one got me good. It outsmarted me and I was fascinated along the way. I especially enjoyed how "Julie's" history was told backward while the rest of story unfolded linearly. It made a nice parallel throughout. By the end of the novel I cared about these characters. This was a solid four star read for me, and while I probably won't return to it, I'd highly recommend it to anyone who enjoys mystery/thrillers.
