I'm on a psychological thriller binge and need some that are really good. I've read some really great ones and some that are...blah. My preference is not about the FBI or CIA type books or the parnormal. I do like murder books with surprise endings and books about those with screwed up brains. (Does this tell you something about me?) I've already read Gone Girl. I was VERY disappointed in the ending. It was very good up until then. While the e nding was a surprise, which I like, I did not like how Nicholas responded to the pregnancy. But that is along the line of the kinds of books I do like only hopefully with scarier endings or more shocking ones. Suggestions?
