This book, the trilogy actually, reads like lightening. I could not click the pages quickly enough! There was one question I never got answered though and that was "Why the dragon tattoo?" Maybe I missed the answer? I don't think so because I kept thinking about it. Maybe it was answered somehow and I was too dense to notice? If someone knows I would love to have their thoughts on this. I love, love, love this series. I was in pain from being so tensed the whole time I was reading. If you have heart trouble you should stay away from these books because it's like a wooden roller coaster ride. It will knock you around and turn you inside out. I loved it.
