Really thrilling and amazing thriller. However, I can't consider it a masterpiece, because of the whirlwind of schemes and plots that were sometimes hard to untangle. It was at times so fast-paced and so confusing, I really didn't have any desire to contemplate about what the heck I've just read, because I deemed it to be too exhausting even to try. I just wanted to keep going, wanted to know what would happen next. If some book can keep me that much on the edge of the seat till the end, I think it's worth reading.
