Cordelia Black is a pharmaceutical rep by day and a vigilante serial killer by night.  She has a code and a system of disposing of her prey.  She is very much a lone wolf with the exception of her best friend, Diane, and goddaughter, Sugar.  The tension and twists in this tale kept me on the edge of my seat.  Watching Cordelia try to escape her wretched past and maintain her daytime facade was exhilarating.  I read the whole thing in one sitting.  I wish the ending could've gone a slightly different direction, but was still thoroughly happy with the story as a whole.  This is a great book for people who love Dexter Morgan.  Thank you NetGalley, Poisoned Pen Press, and Emma C. Wells for this ARC.  All opinions are my own.
