The story is a mystery novel. The main character, Mikael Blomkvist, is a journalist who was hired by a rich old man to take another look at the disturbing disappearance of a family member. A second main character, Lisbeth Salander, is a computer hacker with lots of *personal* issues due to its own sad life story. Being misunderstood from young age, and exploited in later parts of her life, she has very little trust in about basically everything that society has to offer: the authorities, work colleagues, and consequently has almost no friends to relay on. However, being highly intelligent, she manages to get through life in very original ways.As expected in the genre, the books starts by jumping from Mikael story line, to Lisbeth's plot, and eventually both stories intersect and a joint story-line emerges. Two things that I've noted while reading: First, in contrast to many similar novels that usually takes several background chapters before they become interesting, this books is very engaging from the first pages. This is probably due to Lisbeth, who is a very original and interesting character. Second, the flow and pace of the book is great: it starts interesting, and half way through you simply cannot put it down as you want to see what happens next. Lisbeth's character is very interesting, and it is especially intriguing to learn her way of thinking about different issues, and her biased, yet logical view of reality.Great fun, read and enjoy. By the way, I know there is a (Hollywood) movie around the corner for the book. However, I think that in this case I recommend reading the book before watching the movie, as I'm not sure that a movie script can make a good case of presenting Lisbeth's unique thought process.
