I actually liked this until towards the end. In order to explain what took this from a four-star rating for me to a two-star one, I have to mention a few spoilers, so please proceed with caution. 
 (view spoiler)[I get that the crimes of murder and rape are central to this story, but four murders with rape and forced sodomy, with a fifth rape where the victim survives was a lot. Add in a video in which the perpetrator videotapes himself in act, and then on top of that a scene where the video is played and character narrates it while watching. . . I hit a wall. I wouldn't call it a wall of revulsion, but it was definitely a feeling of, "Okay, this is way, way too much." I guess that last thing just made me want to stop, and I basically skimmed to the end after that. 
 I know the series I'm reading - sexual crimes are going to be a part of it, at least in background, considering Eve's history, but this one had it everywhere - I simply shut down after a bit. (hide spoiler)] So, yes, that brought it down to two stars for me. 
 I'll keep on reading, though. Love this series, but if I run into this much of a certain thing again, I likely will skip to the next book.
