This will be a quickie. When I first started listening, I was thoroughly confused. I didn't know what was going on. It kind of reminded me of that movie with Val Kilmer and they were in a building and it was all one big experiment. I don't remember the name of it, just that Val Kilmer and possibly LL Cool J were in it.Anyways, as the book progressed I started getting super paranoid for Benson. Everyone in this place is nuts. There was a decent amount of action, and so many mind games I kept coming back for more. A few events completely took me by surprise. The biggest one being the ending. Holy wow! Cliffhanger galore! I need to pick up the sequel and see what happens next.Definitely for those looking for something different, and a thriller.
