This is a great sequel to "Dragon Tattoo", a definite must-read if you liked the first book.
This time round we finally discover more about Salander, she's slippery as an eel and so much smarter than any other character. It was a joy to have such a brilliant female protagonist, if only other books had strong women characters like her.
Blomkvist is again stubbornly digging away to find the killer, but now he's not so morally upstanding and he's willing to bend a few rules and lie to get what he wants.
The story moves at a fast pace, and it kept me turning the pages even at 2am. The blond hulk was an amusing character, in that he seemed out of this world - the boxing match was great!
Perhaps it's not a good idea to read this book without reading the first book, as there were quite a few references to the previous story and there was only scant information about the characters' relationships with each other.
I'm really looking forward to reading the third book, and it seems such a shame that Larsson only produced the trilogy - I would have loved to read more!
