Now that the cat is out of the bag, after the disastrous events of
Del 5 - Luftslottet som sprängdes (2010), there is no turning back. Rather than accepting defeat, Mikael, now, more than ever, must summon up every last ounce of courage to unearth a monumental government cover-up, and the sinister machinations of corrupt jackals, who are all hell-bent on silencing Lisbeth for good. Little by little, the noose around Lisbeth, Mikael, and a handful of defenders, tightens. What will it take to clear the name of Lisbeth Salander, the girl who kicked the hornets' nest?
