Some Stieg Larsson books include "The Girl with the Dragon Tattoo," "The Girl Who Played with Fire" and "The Girl Who Kicked the Hornet's Nest." The three books together are known as the Millennium Trilogy.
"The Girl with the Dragon Tattoo" introduces the protagonists of the trilogy: the titular character, Lisbeth Salander, who is an expert hacker and private investigator with some serious authority issues and an attitude to match, and a disgraced but talented financial reporter. The two are hired by an aging industrialist to open up a missing person case long gone cold. As the duo begins to uncover some of the deeply rooted family troubles that may have led to the disappearance of the industrialist's grand-niece, the reader also learns about similar circumstances that may have shaped Salander's troubled personality.
In the second novel in the trilogy, Salander is a suspect in the murder of a couple about to publish an expose of the Swedish sex-trafficking industry. The journalist, convinced of her innocence despite her violent tendencies and her fingerprints on the murder weapon, is committed to finding the real murderer and clearing Salander's name. In the final novel of the trilogy, Salander has been shot and charged with three murders, but the journalist is now convinced she's more a vulnerable victim of those in power she despises than a murderer, and the two plot to seek true justice.
