The second in the Millenium trilogy.
This book picks up some time after the initial book finished but the two central hero characters are the same. This time we get much greater insight into the illusive character Lisbeth Salander. Through the book elements of her past that have made her the social misfit she is are gradually revealed. You understand much more why she is like she is.
This book is however darker and more brutal than the first. Larsson was himself a campaigner against violence against women following an experience in his own life. This book is more explicit about some of the abuse and the violence more prevalent than in the first book. However as part of a campaign to expose exploitation and abuse of women it does an excellent job.
The narrative is fast flowing with many twists and changes to keep you guessing. It is indeed a shame that Mr Larsson did die so young, he'd have gone on I'm sure to write many more best selling novels. Definitively a thumbs up approval from me.
