I would give this 3 1/2 stars because I was immediately engaged in the story. I found the main character Sara interesting and figured out fairly quickly the common factor between the current victims and Sara's history. That being said I was desperately hoping that the perpetrator was not someone tied to Sara
Lena is a difficult character for me, I find her interesting but the chip on her shoulder is massive and frankly it's a little annoying the rate at which she can screw up solely based on the fact that she can't seem to pull her head out of her ass. I also feel like I missed a crucial piece of information regarding why Lena obviously dislikes Sara.
Jeffery, the Chief of Police, thus far there is nothing about this guy that I like. He needs a swift kick in the head.
Overall, I enjoyed the story. Although "enjoyed" seems an odd descriptor considering the amount of mayhem and graphic violence that is described. If you are easily made squeamish this may not be the book for you as the author seems to delight in providing graphic details related to the rapes that occurred either during the rape or having conjecture provided during the autopsies.
