This book was a little disappointing when compared to Human.4. It took me till about halfway through before I really got into it. This was a super fast read for me, only took about a couple of hours. The characters were a little weak for me but the premise and plot were really good. I loved the ending of this book. I definitely think that the crazy guy that Peter saw was one of the aliens. I would recommend this to anyone that likes a sci-fi thriller.
