bookworm way of things

I am hesitating between 4.5 and 5. I am not objective. I adore everything related to theme of serial killers and social deviance.(yes, hello Dexter, Criminal minds and Silence of the lambs). I hunt killers is right up my alley (dark and disturbing one). I liked that the story wasn't much about detective itself but about psychological aspect of killing and how sociopaths behave. It was a little disturbing looking though their eyes. Yes, Jazz is a sociopath, albeit a tightly suppressed. It is no wonder with his upbringing. I hunt killers raises a good question - what makes us the way we are. Is it Genetics, upbringing our surroundings or the decisions we make? Is Being raised by serial killer and being tough by him and molded into ideal killer automatically make you one? I deducted half a point because I guessed who the Impressionist was from first half of a book. But book leaves several questions unasked what really happened to Jazz' mother and who Billy contacts were. It is a good thing that this isn't series, a rarity nowadays. The plot leaves just the right amount of information for guessing. I will definitely check out other books of this author.
