Seriously messed up characters. EVERYONE in that book belonged in a mental asylum, no exceptions. Very disturbing. We have the Criminal Master Mind that wants to dole out punishments on anyone that annoys her, murder is also a form of punishment. And everything is done so faultlessly and efficiently, you'd think she's spring cleaning. Psychopath. 
 We also have the Passive-Aggressive with severe daddy issues. And the obsessive freak that probably has a shrine of his object of desire in his home. 
 Mind-Fuck, I felt like I needed to see a shrink after finishing the book. The plot was interesting and unique, no dead spots. The author must be disturbed herself to think up such fucked up characters, no really the "heroine", for lack of a better word, is frightening, I was scared of her. I was also a bit worried when I found myself agreeing to some of her concepts and applauding her for her thorough planning... including murder, not sure what that says about me! 
 I enjoyed this book, although would be taking a little break from psychotic mysteries for a while.
