Woah. This book took me on a RIDE. I would truly recommend going in blind if at all possible, I feel like that is the only thing that could have made the book even better for me. Regardless, this was one of the best thrillers I have ever read, and I have read a LOT of thrillers. Read this in one sitting and loved every minute of it. I will say it took a few chapters to really grip me, but once I kind of got a sense of what was going on (which took like 2-3 chapters max) it was absolutely thrilling all the way to the end.
