I could not put this down. 

I got through the entire book in one sitting and was obsessed. 

But the more I thought about it, the more muddled it all became, and the less I understood WHY I was obsessed. 

The ideas behind the killings was absolutely what caught my attention, but we really don't learn much about the killings in general.
This book is very centered around the psychological ideals behind the murders and got a little obscure at times, but it was also so interesting that I couldn't get enough. 

I think, at the end of the day though, that maybe this book was trying to do too much, and to connect too many dots because there were a few tikes that it got to be a little convoluted. 

I'm absolutely reading the next book, like right now. I need some answers after everything that was hinted at and implied at near the end.
