I actually really enjoyed the slow build for the suspense. I just wish there was more of an explanation for the ending, though it could go on to be a second book. (I don't want it to be..) It's not that I didn't understand what happened, I just wanted a touch more.
Well written and a good suspense book. I feel like this is closer to what The Good Girl by Mary Kubica was trying to do... Heaberlin did it better and less predictable.
