The girl who kicked the hornet's nest, by Stieg Larsson

This book ends the Millenium trilogy, and like the other two was an absolute page turner. The most amazing thing was that the author was a periodist himself, and this incredible well written, well thought, and entertaining trilogy was his first and last attempt at writing fiction. Unfortunately he died before seeing his work published, and thus didn't know the amazing success his books achieved.
In the first book, "The girl with the dragon tattoo", we encounter the apparent protagonist of the trilogy, periodist Mikael Blomkvist. Mikael has fallen in disgrace after a businessman sued him for diffamation, and is threatened with the end of his career and the ruin of his magazine. At this time a mysterious millionaire hires him to resolve a mystery that happened thirty years ago.
Then we are introduced to Lisbeth Salander, an antisocial hacker who helps Mikael with his investigation. Lisbeth is an enigmatic character: withdrawn, highly intelligent, but subjected to a number of abuses throughtout her life.
In the second book Lisbeth is accused of murdering a couple of periodists and her own lawyer/guardian. In the middle of a manhunt we get to know the mysteries of Lisbeth's past and the events who shaped her.
The third book deals with the aftermath of the events that happened in the second book and Lisbeth's trial. Even now she's threatened to be unjustly commited to a mental ward, and it would take all of hers and Mikael's resources to bring the truth to light.
The books are amazing, the plot is thick and convoluted and absolutely perfect to the last detail. My favorite is the second book, because you get to know about Lisbeth's life, and she's in incredible danger all the time, but I couldn't put the third book down. This is a hell of a series, and I highly recommend it.
