This is only my second James Patterson book and is a completely different tone from the first one I read. I enjoyed it a lot and I am quite happy that it was recommened to me. I enjoyed the pov from both the killer and from the people trying to find him. The short chapters made the books feel very fast pace and I found it difficult to put it down. I would recommend to anyone looking for a thriller. It does get a little grusome in spots but if you have read James Patterson before it will not come as a shock. Overall I give it a 4/5.
